Another example. Let's say there's a class that deals with colors.
It has an operator that returns true if two colors look about the
same. Given a list of color objects, is there a regexp to find a

Sweet.
Shouldn't the latter example be:
given baz(@args) { return $_ if $_ > 0 }
In general, if a C condition clause contains
a C<$_>, chances are good that it's a mistake, right?
If a pipe short
Reading A6, I was wondering if the following would work:
sub return_if_true ($value)
{
if ($value)
{
leave where=>caller(1), value=>$value
}
