val compare : t -> t -> int

Comparison function on variables.

val arity : t -> int

Return the arity of the given symbol.

val mk : Path.t -> int -> t

Create a type constant with the given arity.

val get_tag : t -> 'a Tag.t -> 'a option

Get the value bound to a tag.

val get_tag_list : t -> 'a list Tag.t -> 'a list

Get the list of values bound to a list tag, returning the empty list if no value is bound.

val get_tag_last : t -> 'a list Tag.t -> 'a option
