> > Since the style affects default names of primal and dual, I would be a
bit concerned about what happens when a user creates a problem P, then
changes the global style, then dualizes the problem. However, if this can
be done consistently, I have no strong objections to having just a global
style variable.
> There will be some mix of default naming schemes. But: 1) this should
not affect correctness of anything, 2) there will still be an option to
override names, 3) I don't see it as a use case. I think that the most
likely situation is that users will use whatever style is the default one
(so there is some sense in picking "the most common one" as the default).
Those who do figure out the style option are most likely to use it in the
beginning of a session and roll with it. Those who discover it midway will
likely still put it into beginning and rerun all commands. I don't have
any facts to support these speculations, of course, but I will be
surprised if they are wrong.
> My plan for tomorrow is to implement the dictionary approach for the
names. And get rid of `style` argument if I manage to convince you about
it ;-)
OK, fine.
