I still wonder why you think it is so confusing to use the equality sign for module bindings. It is overloaded to mean "define as" and "assign" in almost all language that use it for the latter, and for different semantic categories, too. I never witnessed anybody being confused by that. I agree, though, that '=' is somewhat weird with a plain string on the RHS (but so is 'is'). Personally, I could get used to that, but maybe some variant with 'at' is more appropriate. /Andreas
