`module Excluding_Binders : sig ... end`

The operations of this module substitute variable names that appear in expressions, except for binders, i.e., names on the right-hand side of a `Code.instr.Let`.

`val from_array : Code.Var.t array -> Code.Var.t -> Code.Var.t`
`val build_mapping : Code.Var.t list -> Code.Var.t list -> Code.Var.t Js_of_ocaml_compiler.Code.Var.Map.t`
`val from_map : Code.Var.t Js_of_ocaml_compiler.Code.Var.Map.t -> Code.Var.t -> Code.Var.t`
`module Including_Binders : sig ... end`

The operations of this module also substitute the variables names that appear on the left-hand-side of a `Code.instr.Let`, or as block parameters, or as closure parameters, or are bound by an exception handler.
