Gunter -- your solution is exactly right. I confirmed it, and even changed the 
font of the Question environment without affecting Enumerate, which is why I 
wanted a clone in the first place.

Like you said, I have no idea why the TeX based idiom (using \let) didn't 
work, but it didn't. Your LaTeX based solution works perfectly.

Thanks very much.
