Currently we only have experimental. Maybe we should have one for atscript?

From my #1415 (comment) I would propose:

--es-proposed = --arrayComprehension + --asyncFunctions + --exponentiation + --generatorComprehension

--es-slow or --slow = --symbols

--atscript = --types + --annotations + --classProperties (+ --typeAssertions?)

Then maybe --experimental is a union of all three?

Yes, agree with --atscript, probably without --type-assertions.
