In Squeak there was at least a way to indicate a deprecated method. I
saw it. There was a preference to activate notifications of
deprecations. This possibility should still exist. Maybe we can:

- implement a #peekIf: method with the same source code as current #peekFor:
- depreciate #peekFor: method and call #peekIf: from there to keep compatibility
- wait one or two releases
- change #peekFor: to only peek and conform to standard.

What do you think ?
