[ruby-core:57263] [ruby-trunk - Feature #8921] Allow select, reject, etc to accept a regex

Issue #8921 has been updated by Hanmac (Hans Mackowiak).


1) it can be done via

class Regexp
  def to_proc
    proc {|o| self.match(o) }
  end
end

2) but i think the method you are looking for is grep
%w[foo bar baz].grep /^ba/ # => ["bar", "baz"]

It would be really handy if for instance `select` could accept a regex. For example

```
%w[foo bar baz].select /^ba/ # ["bar", "baz"] 
```

I know that this is currently possible via the slightly longer syntax

```
%w[foo bar baz].select{|i| i[/^ba/] } # ["bar", "baz"] 
```
