Subject: alias_method :tap, :affect


Ruby's enumeration message names come directly from its Smalltalk
ancestry.  There are also some aliases.  Like so:

*method*  *alias*
collect   map
detect    find
select    find_all
reject
inject

Ruby 1.9 introduces the K-combinator in the form of the method
Object#tap.  I don't get the name #tap at all.  So I'm proposing a new
name/alias pair, with a more meaningful name:

*method*  *alias*
affect    tap

"foo".affect { |s| s << "bar" }
#=> "foobar"

The K-combinator is all about side-effecting the receiver object, so
"affect" seems like a meaningful name for that functionality (whereas
"effect" would be wrong!).  "tap" is still cute, and rhymes with "map",
so having both seems like a good Rubyish way to go.

Thoughts?
