in thread Apocalypse 5 and regexes

I have to modify my code quite frequently. When I start using perl 6, I'm not going to want to program in perl 5&6. I have a hard enough time switching between perl, java, and c# ($,;,#,@,/*,// missing when their needed, and there when their not). Usually I'll change one object, or a sub. When this comes around, I'll have to convert an entire program at once, unless they have some funky way of having perl 5&6 code in the same program (although that would probably be bad form).

If I read it right, there'll be a `:p5` modifier to say "interpret this regex according to p5 rules". Quote Larry: So: `m:w/ foo\ bar \h* \: (baz)/` really means (expressed in Perl 5 form): `m:p5/\sfoo bar[\040\t\p{Zs}]:\s(baz)/` I know which of those forms I'd rather use. In general, though, I agree with you that it'd be better to convert an entire program at once instead of piecemeal. Unless you lack time and resources.... Update* Larry explicitly says later in the document: Finally, there's the `:p5` modifier, which causes the rest of the regex (or group) to be parsed as a Perl 5 regular expression, including any interpolated strings. (But it still doesn't enable Perl 5's trailing modifiers.) Should've read more before I typed....	[reply] [d/l] [select]

m:p5/\s*foo bar[\040\t\p{Zs}]*:\s*(baz)*/
