@jlongster@babeljs@sebmck@gnijor Can I use Sweet.js like that? As a behind-the-scenes transform tool?1 reply 0 retweets 0 likes -

@dan_abramov@jlongster@babeljs@gnijor No, you need to invent new syntax for sweet.js macros which is very hostile imo4 replies 0 retweets 0 likes -

@dan_abramov@jlongster@gnijor the types of transforms you can do is also quite basic. Doesn't really lend itself to complex stuff.1 reply 0 retweets 0 likes -

@sebmck@dan_abramov@gnijor this is completely wrong... advanced systems like Racket (which sweet is based on) can even do type inference6 replies 0 retweets 0 likes -

@jlongster@dan_abramov@gnijor With macros it's extremely brittle and if you venture even slightly from what the macro describes it fails.6 replies 0 retweets 0 likes -

@jlongster@dan_abramov@gnijor Also you have no access to scope tracking etc. Extremely limited in what you can do.1 reply 0 retweets 0 likes -

@jlongster @dan_abramov @gnijor Interesting. I've tried to read the sweet.js source multiple times but it's really difficult.
