in thread Can you explain the result?

It makes

open my $FH, '<', $filename or die $!;

and is similar to shell's

mkdir $dir || exit 1

But, of course, you can think whatever you want.

The real problem is that return is pretty different than ordinary subs like open and etc...

[Corion]

return affects control flow, which a function in general cannot (leaving Coro aside). Execution after a function returns will always resume right after where the function was called.

The only built-in function that somewhat affects control flow is exit.
