I definitely think that in terms of error messages rust is what every compiler should aspire to be.
Of course that is kind of necessary since rust has so many unfamiliar concepts and hard to get right syntax. Nim's error messages generally need a bit of detective work to figure out. Once you have some feel for what goes on behind the scenes that doesn't cost much time but it is a barrier to new users and could be a great QoL improvement for experienced users long term. One caveat: it is super annoying to figure out bugs in macros and generally I just recompile with echo treeRepr result before even trying to understand if it isn't trivial. A simple way to output or even render the created ast on compile error would be an amazing and maybe not too complex improvement.
