Hi

could someone please explain this behaviour to me as it is unexpected for me: 

my $regex1 = qr/(?:(?|(?:\")([^\\\"]*(?:\\.[^\\\"]*)*)(?:\")))/;
my $regex2 = qq/(?:(?|(?:\")([^\\\"]*(?:\\.[^\\\"]*)*)(?:\")))/;

my ($match1) =  q|"hubba \"bubba\""| =~ $regex1;
my ($match2) =  q|"hubba \"bubba\""| =~ /$regex2/;

print "$match1\n$match2\n";

__END__
output:

hubba \"bubba\"
hubba \

In the first case I compile a regex immediately, in the second I define a string and only in the line where I match it get's compiled.

I would have expected that the result would be the same - but it isn't...

Why?

Many thanks!
