No. qw(a b c d) prior to 5.6 is defined as split ' ', q(a b c d);
split in a scalar context returns number of elements, and assigns
the split to @_. Had you had warnings on, you'd see that.
qw(a b c d) in 5.6 and later is defined as ('a', 'b', 'c', 'd'), so
you get the value 'd'. "Feh!" to backward compatibility, they
apparently screamed. :)
Hence, Template Toolkit broke in 5.5 because Perrin had done:
my $value = qw(xyz);
to parallel his
my @values = qw(abc def ghi);
above and below. For which us 5.5'ers only got 1, not xyz. :)
I've since beaten him over the head enough times to just use:
my $value = q(xyz);
which works just fine.
