These functions allow to convert back and forth between OCaml and Ltac2 data representation. The to_* functions raise an anomaly whenever the data has not expected shape.

Dynamic tags

Toplevel representation of OCaml exceptions. Invariant: no LtacError should be put into a value with tag val_exn.

Closures

Given a closure, apply it to some arguments. Handling of argument mismatches is done automatically, i.e. in case of over or under-application.

Sourceval abstract : int -> (valexpr list -> valexpr Proofview.tactic) -> closure

Turn a fixed-arity function into a closure. The inner function is guaranteed to be applied to a list whose size is the integer argument.

Exception
