  • Commented on function return in scalar context

  • mauke commented on Converting glob patterns to regular expressions

    Eh, it's generated code. I don't care much about how readable it is. :-)

    I don't think your version handles the last case with backslash escapes.

  • mauke commented on Converting glob patterns to regular expressions

    Text::Glob doesn't treat repeated * specially, no. But it supports many other features (wildcards don't match a leading dot, curlies, etc) plus it uses a rather C-like approach to converting the pattern (iterating over single characters, state machine) so it would take more than 10 seconds of looking at it to make any major changes to the algorithm.

  • Ovid commented on Dave Cross and Modern PERL

    shawncorey: we're not going to use that because that's a part of the system we're no longer using, nor do we need its functionality. I promise you we didn't write that code :)

  • confuseAcat commented on Dave Cross and Modern PERL

    This is ... creative. In our code, I usually just find very, very boring if ( $hour < 9 ) stuff. But modulo 100? Too good to call it PERL.

  • Dave Cross commented on Dave Cross and Modern PERL
