@flowtype @babeljs Babel already handles JSX (even for React itself) and knows how to strip (most?) Flow type annotations. Just saying...

@kpuputti I originally tried to start with esprima (pre-babel), but OOB/serialization showed perf problems :/ @flowtype @babeljs

@lbljeffmo @kpuputti The parser isn't even a bottleneck to full type check support anyway so it doesn't really matter what's used.

@sebmck the parser itself wasn't really the most obvious problem -- it was the machinery to serialize/unserialize interprocess @kpuputti

@lbljeffmo Ah yeah. I was more referring to the notion of Flow somehow being held back by the parser which @kpuputti seemed to allude to.

@sebmck @lbljeffmo Only speculating, but nothing can really keep up with Babel with the current speed.

@kpuputti Eh, I could just stop working on Babel due to burnout, get busy with work, or get hit by a bus. [1/2] @lbljeffmo

@kpuputti You're also underestimating the different complexities involved in something like Flow vs Babel… @lbljeffmo
