active(__(X1, X2)) → __(X1, active(X2))
active(U11(X)) → U11(active(X))
active(U31(X)) → U31(active(X))
active(U61(X)) → U61(active(X))
active(U71(X1, X2)) → U71(active(X1), X2)
active(U72(X)) → U72(active(X))
active(U81(X)) → U81(active(X))
proper(__(X1, X2)) → __(proper(X1), proper(X2))
proper(U42(X)) → U42(proper(X))
proper(U52(X)) → U52(proper(X))
U22(ok(X)) → ok(U22(X))
U42(ok(X)) → ok(U42(X))
U52(ok(X)) → ok(U52(X))
