Source

val prod_applist_decls : 
  Evd.evar_map ->
  int ->
  EConstr.constr ->
  EConstr.constr list ->
  EConstr.constr

In prod_applist_decls n c args, c is supposed to have the form ∀Γ.c with Γ of length m and possibly with let-ins; it returns c with the assumptions of Γ instantiated by args and the local definitions of Γ expanded. Note that n counts both let-ins and prods, while the length of args only counts prods. In other words, varying n changes how many trailing let-ins are expanded.

Sourceval nb_prod : Evd.evar_map -> EConstr.constr -> int

Similar to nb_lam, but gives the number of products instead

Sourceval nb_prod_modulo_zeta : Evd.evar_map -> EConstr.constr -> int
