Let's find out why:
friday:~ $ explain
\G\s*(["'])([^\\\1]*(?:\\.[^\\\1]*)*)\1
[snip]
----------------------------------------------------------------------
[^\\\1]* any character except: '\\', '\1' (0 or
more times (matching the most amount
possible))
----------------------------------------------------------------------
[snip]
As you see, putting \1 in a character class matches the character
"\1". That's not what we wanted; but character classes must be known at
the regex's compile-time.
You could do:
push @matches, $+ while
/\G\s*(["'])((??{"[^$1\\\\]*")(?:\\.(??{"[^$1\\\\]*"))*)/gc or
/\G\s*(\S+)/gc;
But that is ugly, and requires Perl 5.6.0+.
