Package: perl Version: 5.24.1-1 Severity: wishlist This should be made to work:
$ perl -wle '$k=9 x 0xB; print $k if $k =~ /9{0xB}/;' Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/9{ <-- HERE 0xB}/ at -e line 1. In fact the man pages don't say why it shouldn't.
