Re: Fn as value matcher in core.match

It is always matching the first clause because it is getting translated into a `let` binding. In match, the left-hand side `get` is just a symbol, not the `var` it resolves to, so might as well be `(let [fun assoc] (match fun foo "foo!"))` where `foo` will just be bound to `assoc`.
