Subject: A try at allowing matching on applications as a binary syntax node by
 default. It breaks tauto as [?X _ _] matches much more terms. It is mostly
 fixed by not destructing objects of record types. The new [intuition] was
 also pulling an unneeded dependency in Field_theory which can be cleared
 easily. Zis_gcd_bezout is also considered a conjunction now, which seems
 correct(?).
