esprit d'escalier : is now also fixed for R
|
|
The computed proof term is now more explicit exact (__arith P1 ... Pn X1 ... Xm)
instead of apply (__arith P1 ... Pn) which unification could fail.

- Assert a purely arihtmetic sub-goal that is proved independently by reflexion.
(This reduces the stress on the conversion test)
- Does not use 'abstract' anymore (more natural proof-term)
- Fix a parsing bug (certain terms in Prop where not recognized)

If 'abstract' fails e.g. if there are existentials. The tactic runs an abstract-free alternative.

(Fixed #4985)
Lqa.v defines the tactics lra and nra working over Q.

default. Interestingly, there is an example where it makes the rest of
the proof less natural.
Goal forall x y:Z, ...
intros [y|p1[|p2|p2]|p1[|p2|p2]].
where case analysis on y is not only in the 2nd and 3rd case, is not
anymore easy to do.
Still, I find the bracketing of intro-patterns a natural property, and
its generalization in all situations a natural expectation for
uniformity. So, what to do? The following is e.g. not as compact and
"one-shot":
intros [|p1|p1]; [intros y|intros [|p2|p2] ..].

- For instance, refl_equal --> eq_refl
- Npos, Zpos, Zneg now admit more uniform qualified aliases
N.pos, Z.pos, Z.neg.
- A new module BinInt.Pos2Z with results about injections from
positive to Z
- A result about Z.pow pushed in the generic layer
- Zmult_le_compat_{r,l} --> Z.mul_le_mono_nonneg_{r,l}
- Using tactic Z.le_elim instead of Zle_lt_or_eq
- Some cleanup in ring, field, micromega
(use of "Equivalence", "Proper" ...)
- Some adaptions in QArith (for instance changed Qpower.Qpower_decomp)
- In ZMake and ZMake, functor parameters are now named NN and ZZ
instead of N and Z for avoiding confusions

"micromega" et "sos" pour les problèmes non linéaires sous-traités à
csdp); mise en place d'un cache pour pouvoir rejouer les preuves
sans avoir besoin de csdp (pour l'instant c'est du bricolage, faudra
affiner cela).
