>Perl will go about it the exact same way. No, Perl is completely different and IMO it's the only mainstream dynamically typed language that has sane comparison operators. Perl has two sets of operators, numeric (==, +, *, <, >, <=> etc.) and stringwise (eq, ., lt, gt, cmp etc.). You can think of them as explicit (but concise) casts. For example, Perl's $foo eq $bar is roughly equivalent to Python's str(foo) == str(bar). It is true that "foobar" == 0 returns true in Perl but, as I showed above, it does that for a completely different reason. |
