Subject: [ruby-talk:4942] Re: Perl 6 rumblings -- RFC 225 (v1) Data:  Superpositions

Writing an 8-queens program this morning (teaching my 12-year old son about recursion!), I
found that "any" led to an easy translation of "can I put a queen in any of these columns
and get a solution" into concise code which did exactly what I wanted.  (see
http://www.cs.iastate.edu/~slagell/ruby/queens.rb)

At first glance, I like the idea of any/all -- they seem to have broad applicability.

Alternative name suggestions: "any_satisfies" and "all_satisfy" are more descriptive but a
bit long - maybe just adding question marks would be good: "any?" and "all?".
