Backtrack sur la mémoïsation de nf_evar.
L'expérience prouve que ce n'est pas franchement concluant.
On peut se risquer à une explication :
- nf_evar, version mémoïsée n'est pas tail recursive
- On retarde la substitution des hypothèses de l'evar en échange de
faire moins de substitutions d'evars. Intuitivement c'est intéressant
seulement si il y a plus de substitutions d'evar dupliquées que
d'hypothèses dupliquées. Ce qui ne doit pas être le cas (ne serait-ce
que parce que dupliquer une evar duplique aussi ses variables libres).
This reverts commit 066a564021788e995eb166ad6ed6e55611d6f593.
