I have met such use cases, and agree this would be useful.
I don't disagree in the sense that there may be valid use cases,
but the syntax is kind of weird:
/s(?<mid>.)r/
I use regexes a lot of course, since they are useful. But do we
really gain a lot from making what used to be simple, harder?
I understand that you may avoid an extra step (assignment, after
the regex match), but to me personally I find that style so
much harder to read, compared to:
if /(foo.+)/
mid = $1.to_s.dup # or something like that
end
Admittedly I am very much a very oldschool-ruby person. ;)
By the way, while I personally do not really like $ variables,
I actually use them a LOT, whereas I rarely use match_data[]
syntax style. Dunno why, perhaps a habit, but the $1 $2 etc..
are ony of the few (semi) global variables that I like.
(I write "semi" because they tend to be more volatile, which
is why I may tend to use .dup like a semi-crazy person a
lot, rather than fix a regex or handle nils - I .to_s.dup
all the things! ;) )
