imports other than at the top

[Bill Baxter]

I tried sticking an import in a unittest {} block and it caused an error.

I put it there, naturally, because I only needed that particular module 
for the unittests and the whole rest of the file didn't really need to 
see those symbols.  If you're not doing unittests there's no reason for 
the import overhead, and no reason to burden the user with making sure 
that particular testing module is present.

Scoped importing like that just not supported at this time?
