Comment (by ncohen):
> IMHO it's also against the spirit of OOP to have an option in a function
`f` to return either `X` or `X.blah()`; the user can call `.blah()` on the
answer he gets himself; and `X` is already created in `f`, there is no
performance gain in returning X.blah() instead of `X`.
Are we sure that a permuation group defined from a set of generators
returns the *very same* set of generators when you call `.gen()`? Or could
they be simplified/reduced if Gap believe that another representation is
better?
