Number 3 should be the only one you use. Anyone who tries to tell you otherwise shouldn't be teaching you Perl. There's one small exception, you can get away with using number 4, but you should only really use it if you're happy explaining why it's a bad idea.

Number 1 is just weird and number 2 doesn't compile.
