I don't see how that works in my case, maybe i'm missing something. I will clarify:
I define a variable in web to represent the range: 14502..14520 The web converts this to a string, and passes it into my code. My code then has to receive this string, and then construct a list from it. I could do: String rangeString = passedInVar (String min, String max) = rangeString.tokenize("..") Range range = min..max But i was hoping for a universal "caster" loop which can detect and cast the common types from strings: Integers, lists, ranges, maps, booleans.. 12345 ["this", "is", "Sample", "List"] 14502..14520 ["key":"value","for":"maps"] true I think eval works for all but ranges.
