eval and (infinite) recursionI'm implementing an "eval" function in a scripting language... or at least contemplating it. I can envision the infinite recursion from as simple a thing as the sequence: set a to "a" if by eval I mean do variable lookup for strings, and the eval is a "deep" eval. Is one always obliged to make the eval a 1-level shallow eval? Or is eval() generally not a variable-lookup operator? I could provide a separate one, an explicitly shallow evalWithLookup() or something...
