Module Core.Unif_ruleSource

Symbols and signature for unification rules.

This module provides a signature to be used to handle unification rules. The signature is not attached to any real lambdapi file and is henceforth qualified to be a "ghost" signature.

Sourceval equiv : Term.sym

Symbol "≡".

Sourceval cons : Term.sym

Symbol ";".

Sourceval unpack : Term.term -> (Term.term * Term.term) list

unpack eqs transforms a term of the form cons (equiv t u) (cons (equiv v w) ...) into a list [(t,u); (v,w); ...].

Sourceval mem : Term.sym -> bool

mem s is true iff s belongs to sign.
