| Pmakearray of array_kind * Asttypes.mutable_flag

For Pduparray, the argument must be an immutable array. The arguments of Pduparray give the kind and mutability of the array being *produced* by the duplication.

val iter_head_constructor : (lambda -> unit) -> lambda -> unit

iter_head_constructor f lam apply f to only the first level of sub expressions of lam. It does not recursively traverse the expression.

val shallow_iter : tail:(lambda -> unit) -> non_tail:(lambda -> unit) -> lambda -> unit

Same as iter_head_constructor, but use a different callback for sub-terms which are in tail position or not.

val transl_prim : string -> string -> lambda

Translate a value from a persistent module. For instance:

transl_internal_value "CamlinternalLazy" "force"
val free_variables : lambda -> Ident.Set.t
val transl_module_path : Location.t -> Env.t -> Path.t -> lambda
val transl_value_path : Location.t -> Env.t -> Path.t -> lambda
val transl_extension_path : Location.t -> Env.t -> Path.t -> lambda
val transl_class_path : Location.t -> Env.t -> Path.t -> lambda
val make_sequence : ('a -> lambda) -> 'a list -> lambda
val subst : (Ident.t -> Types.value_description -> Env.t -> Env.t) -> lambda Ident.Map.t -> lambda -> lambda

subst env_update_fun s lt applies a substitution s to the lambda-term lt.

Assumes that the image of the substitution is out of reach of the bound variables of the lambda-term (no capture).

env_update_fun is used to refresh the environment contained in debug events.

val rename : Ident.t Ident.Map.t -> lambda -> lambda

A version of subst specialized for the case where we're just renaming idents.

val map : (lambda -> lambda) -> lambda -> lambda

Bottom-up rewriting, applying the function on each node from the leaves to the root.

val shallow_map : (lambda -> lambda) -> lambda -> lambda

Rewrite each immediate sub-term with the function.
