Subject: Named backreferences with Oniguruma

Hi all,

Ruby 1.8.4
Oniguruma 2.5.6

I'm trying to figure out how to get at named backreferences with
Oniguruma, but I'm having some problems figuring it out.  Here's the
interface I would *like* to have:

# pseudo.rb
str = "hello world"
reg = /^(?<first>\w+?)\s(?<last>\w+)$/

match = reg.match(str)

first = match[:first]
last  = match[:last]

But this doesn't work - I mean, the regex works, but the way I'm trying
to get at the backreferences does not.  Nor does there appear to be
anything like Python's MatchData#groupdict() method (which returns a
hash).

How do I get at the named backreferences from the MatchData object?  Is
there a way?

Thanks,

Dan
