Subject: very simple question about enum.all? and any?

%w{ ant bear cat}.all? {|word| word.length >= 3}   #=> true
%w{ ant bear cat}.any? {|word| word.length >= 3}   #=> true

Both of these return true or false as expected. The question is
is there an equivalent method that returns the original enum object
itself (instead of just "true") if the test is satisfied? And nil or
false
if otherwise?

I know code for this can be easily written, but the reason for the
question is a matter of style; because it would be
really nice not to have to specify the enum object more than one
time if the test is satisfied.

For example, in simple english, the "any" test would be: "If any item
passes the test, then return all of the items".
