Of course we do get ahead of ourselves when we discuss or code for extensions. But the open source phenomenon brings out creative energies that are valuable because of the ideas created AND because any one who works on it usually does other work that fits in the mainline. Sometimes, not always, but sometimes if you quash the creative endeavor you loose the other part, the mainline part where they fix some other thing to squeeze their idea in. So I hope that we can evolve a way to capture it, but still allow for a compiler that is straight laced as a variant.
Many innovations are relevant.
I hate to use reference modification for string scans. So you have to take the matter into your own hands often. And it would sure be nice to reference the dataname itself and not have to have convoluted syntax. I would exit the 1950s at long last. As long as you have type information percolating up in the parser it is a piece of cake.
