substitute0 f beta_reduce t

Sourceval substitute : (int -> t) -> t -> t

substitute f term substitutes each free variable i in term by the term f i.

Sourceval substitute_with_beta : (int -> t) -> t -> t

substitute f term substitutes each free variable i in term by the term f i and do beta reduction in case that f i appears in a function position and is a function abstraction.
