Ehh?  No, it isn't.  I never understood the use of the word 'transaction' 
in libzypp (or "an item transacts", which gives me even more creeps).  A 
transaction is a collection of units of work, not a collection of things.  
A unit of work, when applied to a thing gives you a new think, hence a 
transaction is comparable to a function, and the pool comparable to a 
simple set on which a transaction can be applied (giving you a new pool).

(For nitpicks: yes, a function also is just a special set, but it's 
cleaner to differentiate between both concepts).

I hope you reconsider.  My toenails curl up when I hear that :)


Ciao,
Michael.
