In that case I'd prefer the real block as Charlie suggested. ---------------------------------------- Feature #7883: Add Regex#to_proc https://bugs.ruby-lang.org/issues/7883#change-36606 Author: rklemme (Robert Klemme) Status: Open Priority: Normal Assignee: Category: core Target version: 1.9.3 Just a small addition to the standard library: class Regexp def to_proc; lambda {|s| self =~ s} end end With that one can use a Regex everywhere a Proc is used as filtering criteria saving a bit of typing. While we have Enumerable#grep already there may be other cases where you want to do something like irb(main):008:0> %w{foo bar baz}.select &/\Ab/ => ["bar", "baz"] irb(main):009:0> %w{foo bar baz}.reject &/\Ab/ => ["foo"] irb(main):010:0> %w{foo bar baz}.find &/\Ab/ => "bar" Note: line 9 and 10 are not possible with Enumerable#grep AFAIK. I see low risk of breaking something. -- http://bugs.ruby-lang.org/
