in my $x = 10; the = is a scalar assignment which returns the assigned scalar
in my ($y) = 10; the = is a list assignment which returns the number of assigned elements¹ That's a crucial trick for iterators, where returned elements might be false (like 0 , '' or undef). So will work as long as anything (i.e. no empty list) is returned, while can break if you don't use special magics like "0 but true".
Cheers Rolf UPDATE: 1) in scalar context! In reply to Re: list context (iterators)
