Stronger invariants on the use of the introduction pattern (pat1,...,patn).
The length of the pattern should now be exactly the number of
assumptions and definitions introduced by the destruction or induction,
including the induction hypotheses in case of an induction.
Like for pattern-matching, the local definitions in the argument of
the constructor can be skipped in which case a name is automatically
created for these.
