Playing with complex numbers, I can't help but notice that some computations are pretty ugly:

There is a lemma in `Arith` called `Nat.ltb_ge` with the following type:

In the following, the obvious occurence of nested `funcomp` is not found. Instead, `f` is unifed with the identify function and `h` is unified with an application of `funcomp`.

#### Description of the problem
Since SSReflect 1.5, by default the `have` tactic performs typeclass inference over the goal, as [documented](https://coq.inria.fr/refman/proof-engine/ssreflect-proo…

Is there a plan to define order-preserving morphisms and some of their theory?

Can someone (@ggonthier?) explain the use of `seq_eqclass`?

We need a test suite automatically run by CI, and also extensive test cases to detect regressions. I think it makes sense to include `example.v` in it.

The following file triggers the following error with its last tactic:
`Anomaly: cvtac's exception: Logic.RefinerError(_). Please report.`
