Isn't the point of calling env = conf.Finish() not to allow you to set all 
variables in env and test not before calling Finish()?

Right now it works without importing the entire environment. The only import 
I do is about $TERM. Since I do that only for compiler==clang++ it can't be 
done in constructor.
