Sourceval beta_applist : Constr.constr -> Constr.constr list -> Constr.constr

Builds an application node, reducing beta redexes it may produce.

Sourceval beta_appvect : Constr.constr -> Constr.constr array -> Constr.constr

Builds an application node, reducing beta redexes it may produce.

Sourceval beta_app : Constr.constr -> Constr.constr -> Constr.constr

val hnf_prod_applist :

val hnf_prod_applist_decls : 
  ?evars:CClosure.evar_handler ->
  Environ.env ->
  int ->
  Constr.types ->
  Constr.constr list ->
  Constr.types

In hnf_prod_applist_decls n c args, c is supposed to (whd-)reduce to the form ∀Γ.t with Γ of length n and possibly with let-ins; it returns t with the assumptions of Γ instantiated by args and the local definitions of Γ expanded.

val whd_decompose_lambda_n_assum : 
  ?evars:CClosure.evar_handler ->
  Environ.env ->
  int ->
  Constr.constr ->
  Constr.rel_context * Constr.constr

This is typically the function to use to extract the context of a Fix not already in normal form up to and including the decreasing argument, counting as many lambda's as given by the decreasing index + 1
