Summary of exported operations:

unify :: Eq a => [(Term a,Term a)] -> Either (UnificationError a) (FM Int (Term a))   
Unifies a list of term equations.
unifiable :: Eq a => [(Term a,Term a)] -> Bool   
Checks whether a list of term equations can be unified.

Exported operations:

unify :: Eq a => [(Term a,Term a)] -> Either (UnificationError a) (FM Int (Term a))   

Unifies a list of term equations. Returns either a unification error or a substitution.

unifiable :: Eq a => [(Term a,Term a)] -> Bool   

Checks whether a list of term equations can be unified.
