not check if x is real.

But I suppose ask(Q.integer(Symbol('n', integer=True))) will eventually
work, once assumptions will be unified ?
Or will Symbol('n', intege

It's unclear at the moment. See
https://github.com/sympy/sympy/wiki/assumptions. I'd like to keep that
syntax, though, if possible.

IMO, Eq would best fit for a boolean (standing for "equality"), while Eqn

The only problem with this is that Eq() is presently used for equations, so
it would break compatibility.
What would you suggest naming the inequality funct

I think adding two inequalities or differentiate them could be done without
much pain using a Eq.as_expr() method, since Eq(a, b) can alw

+1 for removing this, or at least renaming it.
Current S.Zero.is_finite is extremely confusing, *even if well documented*.
If really needed, maybe a .is_finit

OK. Old assumption system have a nice API, so it would be nice to keep it
as a front-end if possible.

Changing it to Eq(a - b, 0) defeats the whole purpose of having an equality

This will canonically sort the args in a platform independent way.
