Hi --

It's funny that "ifNil: [ ^nil ]; do: [:ea | ... ]" almost looks like the older #ifNotNilDo: but that did not enumerate a collection. :-D Maybe that's the semantics for #ifNotNilDo: that might work.

Object >> #ifNotNil:
Collection >> #ifNotNilDo:

Just a thought. No serious proposal here. #ifNotNilDo: has still semantic baggage. 

Best,
Marcel
