Subject: [ruby-core:57264] [ruby-trunk - Feature #8921] Allow select, reject,	etc to accept a regex


Issue #8921 has been updated by kyledecot (Kyle Decot).


=begin
Yes, grep would be a suitable alternative for `select` w/ a regex in this instance. What about for `reject` though? I feel that

    %w[foo bar baz].reject /^ba/ # ["foo"]

Is more readable than

    %w[foo bar baz].grep /^[^ba]/ # ["foo"]


Using `reject` also makes it so that I don't have to rewrite my regular expression to negate what I'm looking for. My example is pretty trivial but I think that it would quickly get out of hand if trying to grep things "out" instead of "in".

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"] 
```
