in thread return !!

you can save some cycles by not copying the entire data.

Since the context is surely scalar, it wouldn't copy the entire data anyway.

    ikegami,
    I was speaking to the idiom not this specific example. For instance return $foo; where $foo is the contents of a large file. I also am not sure I agree that the author of the sub can be sure that the caller of the sub would be calling it in scalar context - making the explicit scalar useful.

    Cheers - L~R
