Post author here. A few things that make me sad in the pants:

- js doesn't have source maps (kinda of a big deal to me)

- some error messages are head scratchers (seem to remember trying to add things to an immutable array not being clear)

- docs could use love (eg seeing more examples of macros in action)

- devel (their nightly compiler) can be rough (e.g. i found the "strings cannot be null" cutover a bit rocky -- my own damn fault, i can't go back to 0.18 after being on 0.18.1)

- the big one I think, however, is adoption. I keep hearing "i'll just use rust or go". That's legit as they're also awesome.

nim's stdlib is massive (too big?) and there's tonnes of high quality packages out there. You won't be left thinking... well, crap, looks like I need to talk to roll this redis layer myself.

EDIT: Formatting. How does it even work?
