Comment (by ncohen):
Hello !
> `new_variable` has been dropped for this ticket, and the method has been
renamed to `interactive_linear_program` as you suggest.
Thanks!
> The code is indeed GLPK-specific (explicit testing for it has been
added) -- more general support would require designing a common interface
to basis status, which is #18688.
Okayokayokay. For as long as a meaningful exception is raised when the
backend is not one that the code handle, it's fine by me. Especially since
in this case the 'right backend' is GLPK. It's more awkward when the only
backend that supports a feature is one that Sage does not ship by default.
