ROFLMAO the delimiters, of course! I don't think I ever would have figured that out. And that neatly explains the error message, which I hadn't made sense of, yet.

Thanks Dave!

P.S. Don't worry I'm not mad enough to eval untrusted user input, even untainted quite frankly, as I don't think I'm smart enough to untaint perfectly. I'm just doing this for a little utility testing script, which, for the remainder of it's short life, will only be taking input from me personally :-)
