[GemStone-Smalltalk] first: / last:

[via GemStone-Smalltalk]

We've implemented #copyFirst: and #copyLast: on GS and VW for ourselves ... I agree, those are better method names.

Hi Richard, 

just some additional info about API: besides #first: and #last: there’s also #allButFirst: and #allButLast:, which make it extremely easy to access sub-collections without using copyFrom:to:. 

I do however agree that a „copy“ at the beginning of the selectors wouldn’t have hurt.

Kind Regards
Karsten
