Sourceval create : string -> 'a tag

create n returns a tag describing a type called n. create raises an exception if n is already registered. Type names are hashed, so create may raise even if no type with the exact same name was registered due to a collision.

eq t1 t2 returns Some witness if t1 is the same as t2, None otherwise.

repr tag returns the name of the type represented by tag.

    (*

    *)
Sourceval name : string -> any option

name n returns Some t where t is a boxed tag previously registered with create n, or None if there is no such tag.

Sourcemodule Map (Value : ValueS) : MapS with type 'a key = 'a tag and type 'a value = 'a Value.t

Map from type tags to values parameterized by the tag type
