Re: Interpolating Nursery Rhymeby stephen (Priest)

Hmm... you don't use quotes with numbers. '5' and "5" are the same thing-- a string containing the character '5'. If it's in quotes of any sort, it's a string.

One uses double quotes for strings that should have variables interpolated. So:
prints "Bar is 3".
