I've read some pull request why syntax highlighting is like that, but can't you just take reason grammar or something?
Just look at these two screenshots:
Rescript:

Reason:

See? It feels like half of code is just uncolored, variable names, record type fields etc.
Is it that hard to take reason grammar and tweak it for rescript slightly different syntax?
I would very like to stick to rescript. But the way things are now makes me feel like I should wait a year or two, not to demoralize.
