I do agree that I should have reviewed the document before posting a
response.  I have done that, and still hold to what I've stated.

The Perl syntax he proposed is a hideous mess of line noise ( no surprises
).

I don't believe that the suggested functionality can be added without
slowing regular expression matching.

But there IS one idea in the document I like and would require NO changes t=
o
regexp syntax.

# define a normal regex with 1 group
a =3D /(\d+)/

# add a rule for group 1s matching
a.rules << Rexexp::Rule.new( :group, 1 ) { |val| val > 20 }

# now play.
b =3D "200 19 14 21 1"
b.scan a
#=3D>[ "200","21" ]

... at least that's how I'd do it ...  Beyond that, I still feel trying to
get anything more than "ideas" for features from Perl is NOT a good path fo=
r
ruby.

Anyways, I do see value in what you brought to the table ... but maybe next
time explain the feature for it's merits not "hey look what perl is doing!"
...
