Reimplement namespaced identifier to support polymorphic args

This is somewhat of a temporary hack, as a namespaced identifier should
not really refer to types or polymorphic arguments. But we need a
tokenizer and a prepass to properly distinguish identifiers from types.
So it works, but error messages may be cryptic.

composite main(out c) {
	channel ao -> ai;
    channel bo -> bi;
	new sync(ai, bo);
	new binary_replicator(bi, ao, c);
}

    while (true) {
        synchronous {
            if (fires(a) && fires(b)) {
            	msg x = get(a);
            	put(b, x);
            } else {
                assert !fires(a) && !fires(b);
