AFAIK, this would be a pretty serious change.  The compiler just
generates (basically)PyObject_SetAttr() calls.  There is no way in
the current runtime to differentiate between "compile time" and
"runtime" attribute references...  If this was done, it would simply
be ugly hacks to support what can only be described as unpythonic in
the first place!
