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

and is similar to shell's

mkdir $dir || exit 1
[download]

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

`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`.	[reply] [d/l] [select]
