It is still more sensible to have everything end in `Graph` than a
different standard for each function. And, indeed, this standard is awful.
Is this mere a lament? Or a request to change names of functions on this
ticket? Or a proposal to change the standard?

in the literature people write about `T_2^*(O)`, with O a hyperoval in a
plane in PG(3,q).

OK, changed.
