Patch is a rough cut. Requires something in the 4.5.2 alpha/rc series to work.
Posted here because of the hack to avoid having the __call__
function in the derived class not get called during the initialization.
Somewhere (once per invariant, I think) the creation of the optimized quotient module has a "self()" call that reaches all the way down into this class and if the optimized module is used for conversion, it just causes infinite recursion. (Also happens with saving _orig_gens but that is more obvious).
Need for the conversion is described more fully at #9695. Help or advice needed!
