Comment(by rbeezer):
Mystery solved. The `FGP_Module` class will accept an iterable in
{{{__call__}}}, which it uses for a linear combination of a minimal set of
generators. It will also accept a vector (which is a module element) and
use its entries as the scalars in a linear combination of the "original",
"obvious", or "non-minimal" generators. This distinction was hard to
discern in the doctests.
As part of working on other documentation items, I have addressed this at
#9783. So this ticket could be closed once #9783 is merged, if not
sooner.
