Hi, Serhiy.

I could and will, yes: thanks for the suggestion. But for this specific 
feature, I also want to test with simple variable-only expressions. I'm 
either going to use a unicode identifier in the code, or eval one in a 
string. Doing the eval dance just seems like extra work for some sort of 
purity that I don't think is important in a test, unless someone can 
think of a good reason for it.
