why no MatchData#match ?

I use MatchData infrequently enough that I keep being thrown by the
lack of a #match method, to go along with #pre_match and #post_match.
#[0] simply isn't as self-documenting.

Probably because "match" sounds like the MD would be able to match again
(like Regexp.match). If you can come up with an unambiguous name I'd
make it a RCR.

Kind regards

Maybe "MatchData#matched" makes sense.

irb(main):009:0> md = "Hugo is a great dancer!".match(/great/)
=> #<MatchData:0x2b35644>
irb(main):010:0> md.pre_match
=> "Hugo is a "
irb(main):011:0> md.matched
=> "great"
irb(main):012:0> md.post_match
=> " dancer!"

Long considered this, and I've come to think it doesn't matter. In
everyday language we use "match" in multiple contexts, including verb
and noun. I think it's okay if Ruby does too.
