=head1 DESCRIPTION
-The functions exported by this module deal with runtime handling of Perl
-modules, which are normally handled at compile time.
+The functions exported by this module deal with runtime handling of
+Perl modules, which are normally handled at compile time. This module
+avoids using any other modules, so that it can be used in low-level
+infrastructure.
+
+The parts of this module that work with module names apply the same
+syntax that is used for barewords in Perl source. In principle this
+syntax can vary between versions of Perl, and this module applies the
+syntax of the Perl on which it is running. In practice the usable syntax
+hasn't changed yet, but there's a good chance of it changing in Perl 5.18.
+
+The functions of this module whose purpose is to load modules include
+workarounds for three old Perl core bugs regarding C<require>. These
+workarounds are applied on any Perl version where the bugs exist, except
+for a case where one of the bugs cannot be adequately worked around in
+pure Perl.
+
+=head2 Module name syntax
+
+The usable module name syntax has not changed from Perl 5.000 up to
+Perl 5.15.7. The syntax is composed entirely of ASCII characters.
+From Perl 5.6 onwards there has been some attempt to allow the use of
+non-ASCII Unicode characters in Perl source, but it was fundamentally
+broken (like the entirety of Perl 5.6's Unicode handling) and remained
+pretty much entirely unusable until it got some attention in the Perl
+5.15 series. Although Unicode is now consistently accepted by the
+parser in some places, it remains broken for module names. Furthermore,
+there has not yet been any work on how to map Unicode module names into
+filenames, so in that respect also Unicode module names are unusable.
+This may finally be addressed in the Perl 5.17 series.
+
+The module name syntax is, precisely: the string must consist of one or
+more segments separated by C<::>; each segment must consist of one or more
+identifier characters (ASCII alphanumerics plus "_"); the first character
+of the string must not be a digit. Thus "CIO::File", "C<warnings>",
+and "Cfoo::123::x_0" are all valid module names, whereas "CIO::"
+and "C<1foo::bar>" are not. C<'> separators are not permitted by this
+module, though they remain usable in Perl source, being translated to
+C<::> in the parser.
+
+=head2 Core bugs worked around
+
+The first bug worked around is core bug [perl #68590], which causes
+lexical state in one file to leak into another that is C<require>d/C<use>d
+from it. This bug is present from Perl 5.6 up to Perl 5.10, and is
+fixed in Perl 5.11.0. From Perl 5.9.4 up to Perl 5.10.0 no satisfactory
+workaround is possible in pure Perl. The workaround means that modules
+loaded via this module don't suffer this pollution of their lexical
+state. Modules loaded in other ways, or via this module on the Perl
+versions where the pure Perl workaround is impossible, remain vulnerable.
+The module LLexical::SealRequireHints provides a complete workaround
+for this bug.
+
+The second bug worked around causes some kinds of failure in module
+loading, principally compilation errors in the loaded module, to be
+recorded in C<%INC> as if they were successful, so later attempts to load
+the same module immediately indicate success. This bug is present up
+to Perl 5.8.9, and is fixed in Perl 5.9.0. The workaround means that a
+compilation error in a module loaded via this module won't be cached as
+a success. Modules loaded in other ways remain liable to produce bogus
+C<%INC> entries, and if a bogus entry exists then it will mislead this
+module if it is used to re-attempt loading.
+
+The third bug worked around causes the wrong context to be seen at
+file scope of a loaded module, if C<require> is invoked in a location
+that inherits context from a higher scope. This bug is present up to
+Perl 5.11.2, and is fixed in Perl 5.11.3. The workaround means that
+a module loaded via this module will always see the correct context.
+Modules loaded in other ways remain vulnerable.

=item $module_name_rx
Matches a valid Perl module name in bareword syntax.
-The rule for this, precisely, is: the string must
-consist of one or more segments separated by C<::>; each segment must
-consist of one or more identifier characters (alphanumerics plus "_");
-the first character of the string must not be a digit. Thus "CIO::File",
-"C<warnings>", and "Cfoo::123::x_0" are all valid module names, whereas
-"CIO::" and "C<1foo::bar>" are not.
-Only ASCII characters are permitted; Perl's handling of non-ASCII
-characters in source code is inconsistent.
-C<'> separators are not permitted.
