Replying to [comment:5 SimonKing]:
> Another question: What is the reason for having
`CombinatorialFreeModule` in `sage.combinat`? Is it just since the author
is a "combinat guy"? I actually never understood the adjective
"combinatorial" in `CombinatorialFreeModule`---what is it, in contrast to
just any `FreeModule`, and is there a compelling reason for not having it
in `sage.modules`?
It's just how Mike Hansen named it back in 2008. It definitely should be
in `sage.modules` (typically in `sage.modules.with_basis`) and be called
`FreeModule(QQ, I)`. See #10673.
