I proposed this some one or two years ago. I got shut down, but I still find it a good idea.

And I even have a semantic reason:
- A Block represents a piece of functionality that can be evaluated with some input
- A Symbol often represents a selector which in turns represents a piece of functionality that can be evaluated with some input.

I seem to recall there was discussion some time ago about splitting Selector functionality from Symbol. After all, there's no real reason that a selector has to be a Symbol.

Also, some of the examples in this thread seem to be about terseness for terseness sake.
