Group names in regular expressions

[donn]

Given the following regex to parse telephone numbers:

/^(\(?(?<area>[0-9]{3})\)?)?(\-| )?(?<exch>[0-9]{3})(\-|
)?(?<party>[0-9]{4})/

Is there a regex.method to access the parse data by group name? I was
hoping something like the following behavior:

rx = /^(\(?(?<area>[0-9]{3})\)?)?(\-| )?(?<exch>[0-9]{3})(\-|
)?(?<party>[0-9]{4})/
md = rx.match('800 325-3535')
puts md['area']+md['exch']+md['party']

I'm not that skilled with regex (yet), so I don't know if I could
extend the regex class with my own method. I'm not sure what all data
is available to me after parsing.

With Ruby's builtin regex engine? No. With Oniguruma (or the Ruby 1.9
branch)? Yes.
