Feature #10645: Consider adding support of .first to MatchData object like MatchData[0]

Hi,

Lately I was using match data

test_string = "

This is heading 6

"

match = /<h\d+>(.+)</h\d+>/.match(test_string)

Then I tried to do this:

puts match.first

It did not work.

puts match[0]

Is the way to go.

My question is:

Would it be consistent to consider adding
support of .first to MatchData as well?

class Array has it - I kind of assumed that
MatchData is a bit similar to Array.

Thanks,

The question is how similar exactly. What other array methods would you expect? MatchData has a to_a method, so it can be treated as an array. Should it be changed to include Enumerable? Enumerable would have #first, and many other methods.
