I have two questions/suggestions regarding regex syntax: 1) The :ii modifier is influenced by :sigspace modifier. IMHO this is ugly, because the matching part and the replacement part of a regex should be as orthogonal as possible. Therefore I'd like a different syntax for :ii :sigspace, maybe :smartcase (I'm always bad at inventing names, so please come up with different suggestions), or :ii :smartcase or some such. Any comments?
2)
I noticed that in larger grammars (like STD.pm and many PGE grammars in
the parrot repo) string literals are always quoted for clarity
regex foo {
'literal' <subregex>
}
Since I think this is a good idea, we could just as well enforce that, and
drop the <...> around method/regex calls:
regex foo {
'literal' subregex
}
This way we'll approximate "normal" Perl 6 syntax, and maybe even improve
huffman coding.
I guess such a syntax wouldn't be acceptible in short regexes, which are
typically written as m/.../, rx/.../ or s[...][..], so we could preseve
the old syntax for these regexes.
Do you think it would be worth the effort of maintaining (and teaching)
two different regex syntaxes?
(If this has been proposed and rejected before, please just tell me, I'm
only following Perl 6 development for about a year).
Cheers,
Moritz
