Let's say:
x = "foo"
But now I want to see if foo itself is an assigned variable (i.e. foo ~= nil --- but since I don't know the sting contained in x, I can't do this directly)
So is there someway to find out if a string (held in a variable) is also a variable, and if so, is it possible to get at the contents of that variable?
