op Type.--> : hol_type * hol_type -> hol_type

Right associative infix operator for building a function type.

If ty1 and ty2 are HOL types, then ty1 --> ty2 builds the HOL type ty1 -> ty2.

Failure

Never fails.

Example

- bool --> alpha;
> val it = `:bool -> 'a` : hol_type

Comments

This operator associates to the right, that is, ty1 --> ty2 --> ty3 is identical to ty1 --> (ty2 --> ty3).
