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:

        m:w/ foo\ bar \h* \: (baz)*/ really means (expressed in Perl 5 form):
        m:p5/\s*foo 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....

    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....
