DESCRIPTION:We provide a generic categorical setting for Miller's\npattern
  unification. The syntax with metavariables is generated by a\nfree monad 
 applied to finite coproducts of representable functors\; the\nmost general
  unifier is computed as a coequaliser in the Kleisli\ncategory restricted 
 to such coproducts. Our setting handles\nsimply-typed second-order syntax\
 , linear syntax\, or (intrinsic)\npolymorphic syntax such as system F.\n\n
