So what? The Python language uses English words. "as" is the wrong
semantic and should be rejected based on that. But not because it is

Next, you'll say that we should replace "import", "class", and "assert"
with funny little characters. Soon enough, we'll end up with APL or Perl.

Yes. I recommend '!' for the operator and ':' for the funcdefs.

I don't follow your question here. I don't understand your distinctions
between dynamic and runtime and static...
