//test("a:1;b:a+;a:2;b 3", "4");
// clear up application/dict ambiguity.
// f[a:1] is f.,(a:1)
// f [a:1] is f.,[a:1]
// I need to unify the two definitions of nil floating around currently
// verb-func unification?
// This would simplify a great deal of dispatch logic and remove the need for
// amend/dmend/query to be special syntactic cases.
