This and other RFCs are available on the web at http://dev.perl.org/rfc/ =head1 TITLE Require explicit m on matches, even with ?? and // as delimiters. =head1 VERSION Maintainer: Nathan Torkington <[EMAIL PROTECTED]> Date: August 20, 2000 Version: 1 Mailing List: [EMAIL PROTECTED] Number: 135 =head1 ABSTRACT C<?...?> and C</.../> are what makes Perl hard to tokenize. Requiring them to be written C<m?...?> and C<m/.../> would solve this. =head1 DESCRIPTION Damian Conway's Text::Balanced module does a pretty good job of tokenizing Perl code. However, bare C</.../> and C<?...?> require semantic analyis to distinguish them from division and the hook (C<A?B:C>) operator. To remove this hassle, and thus permit programs that analyze the source-code of other programs, I propose requiring that all matches require an explicit C<m>. =head1 IMPLEMENTATION Remove the bare C</.../> and C<?...?> from the grammar :-) When converting perl5 programs to perl6, put the C<m> in. =head1 REFERENCES perl6-language message C<[EMAIL PROTECTED]> by Damian Conway
