Subject: [ruby-core:27961] RCR: allow {select, collect, map} to accept symbol argument

Background.

Currently in order to avoid using braces and to use select/map et al,
one must do

collection.map &:symbol

This is quite explicit, which is good, however the syntax is somewhat
ugly, which is surprising (mostly because the punctuation is
somewhat...hard to read, at least for this Ruby reader).

Suggestion:

Allow map/etc al to accept a single argument, and convert it implicitly to proc.

collection.map(:symbol)

This reads more easily.

Another option would be to add map_by(arg) and collect_by(arg)

which would actually be more preferable, as least for me.

Thoughts?
Thanks.
