# qr/{,n}/ is now accepted

I find this code very unfortunate, what does it mean if the empty string can be repeated n times?

This could better be either a syntax error. But I'm rather expecting Perl not reading the curlies as metas.

from the delta

An empty lower bound is now accepted for regular expression quantifiers, like {,3}.

so {,3} is the same like {0,3} or {1,3} ?

please elaborate!

edit

to demonstrate my point

  DB<8> $re = qr/{0,3}/

  DB<9> p "" =~ $re

  DB<10> p "{0,3}" =~ $re
1
  DB<11> p $]
5.032001
  DB<12>

  DB<13> use warnings; use strict; my $re = qr/{,3}/

  DB<14>

the curlies are taken literally!

qr/{,3}/ was always allowed.
