I agree with all of this; but the fact that a feature can be abused doesn't mean that it is bad, right? for example, being able to use virtually any character in lisp identifiers is nice; yet we don't encourage anyone to write (let ((\(\'\) 1)) (print \(\'\))).

I fully agree.  I find it very nice for simple pieces of code, that's all.
