Bug#857516: repeat counts should be able to use hex

[積丹尼 Dan Jacobson]

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.
