Re: perl popularity inside openbsd community? (Re: Suggestion: Replace Perl ...)

True, but I think it's cleaner when you're actually calling the function to not have to send a hashref. Small thing, of course, but I figure you write a function once, but call it many times. I'd rather the function call be cleaner/simpler than the function definition for that reason.
