fixing badly named variables is not a bug fix either, but that has happened in 
python 2.7. A micro change release changed

compiler.consts.SC_GLOBAL_EXPLICT

to

compiler.consts.SC_GLOBAL_EXPLICIT

this is a change of api for the consts module (if you regard exported variables 
as part of its api), but that didn't count for the developers.
