Hi igor

do you understand why the previous definition was

cachedDefinitions Definitions ifNil: [Definitions := WeakIdentityKeyDictionary new. WeakArray addWeakDependent: Definitions]. ^ Definitions

i don't. :)

It just a way to free memory as fast as possible. But its really not worth spending so much CPU in order to save few bytes of memory.

:) I looked a bit at the code and it is used just so that MCDefinition flush them if they are not already GCed. So I understand. Stef
