Comment (by nthiery):
Just some first feelings; I have only skimmed through the discussion, so
please take them with a grain of salt!
About AGenericIwahoriHeckeAlgebra:
- +1 on ``it should not be in the global name space''
- +1 on ``it should not be in the Hecke algebra name space (i.e. appear in
the tab completion on Hecke algebra'')
- +1 on it appearing *somewhere* in the reference manual
With this in mind, I guess I would put it in the same module as it is now,
but not as a nested class. And maybe change the class name to be explicit
about the choice of parameters not being what people would call ``the
generic ones''?
Oh, and a stupid idea: would it make any sense for the Hecke algebra to
have lift/retract maps to the "generic" one, and reference the later as
"ambient" like we do for subquotients ?
See:

Cheers,
Nicolas
