I do not believe that is universally true is 2.7.  But even if it is...
Short ints were, value-wise, a subset of longs.  Thus, for example, 
binary operations could always convert the int to long and continue.  In 
3.0, short ints were removed and long renamed int.

That would require an O(n) check.  Bytes and unicode have an ascii 
overlap when bytes are interpreted as ascii chars, but neither is a 
subset of the other.  Mixed binary operations were removed in 3.x.
