When people want to import modules with "runtime" names, they regrettably turn to __import__() and likely will for a while.  What a source of headaches!

If it were less convenient to use __import__(), perhaps fewer people would use it.  Could we remove it from <module>.__builtins__, so that it would not be found during the lookup chain?  We could still expose it in the builtins module or move it to imp.
