# New Ticket Created by Father Chrysostomos # Please include the string: [perl #128241] # in the subject line of all future correspondence about this issue. # <URL: https://rt.perl.org/Ticket/Display.html?id=128241 > It often comes up on the list that /$foo/ is subject to re-use of the last match if $foo is empty, and most people then admit that it was a mistake, and that the last match should be used only when the // is syntactically empty. (I believe we have consensus on this, but I may be mistaken.) Because of backward-compatibility, we cannot simply change it, but we could emit a deprecation warning whenever /$foo/ uses the last successful match. I suspect this will catch many bugs in people’s code. After the deprecation cycle, we can make /$foo/ behave the same way as /(?:$foo)/. -- Father ChrysostomosThread Previous | Thread Next
