 I can't think of user-visible Python syntax for such a redefinition, and 
my lack of knowledge of the language does not help either, so someone more 
experienced in this area would have to step in.  It would be great to have 
the ability to add arbitrary keywords from Python code too I suppose.

 And the old keywords have to stay anyway, just as I have retained, e.g. 
`add_setshow_zuinteger_unlimited_cmd' in C++ code so that callers do not 
have to repeat an explicit reference to `zuinteger_unlimited_literals'.
