Nobody has figured out the semantics of single alias this, either (when faced 
with class inheritance). The bugzilla issues for it are ample evidence.

MI is a Hansel and Gretel feature, where it appears to be all gingerbread and

Other Hansel and Gretel features:

1. monkey patching
2. macros
3. implicit variable declaration
4. preprocessor
