Module RetypingSource

This family of functions assumes its constr argument is known to be well-typable. It does not type-check, just recompute the type without any costly verifications. On non well-typable terms, it either produces a wrong result or raise an anomaly. Use with care. It doesn't handle predicative universes too.

The "polyprop" optional argument is used by the extraction to disable "Prop-polymorphism", cf comment in inductive.ml

The "lax" optional argument provides a relaxed version of get_type_of that won't raise any anomaly but RetypeError instead
