Different projects require different tools. Approaches used for 1) Low-Level and System Programming are different from 2) High-Level and Application Development.
Nim community is heavily biased towards 1 kind of projects. And topics like Zero-Overhead, GC, Soft-Realtime, etc. cause lots of discussion in this forum. Things important for App Dev are different, things like Time to Marked (Simplicity and High Productivity, you had to develop and launch the App before your competitors do), Low Risk and No Surprises (it's ok if App going to consume x2 more memory or even x4, it's not ok if it's going to crash or behave unpredictably), etc. I think things needed for App Development are neglected by Nim community. Like this topic, about simplification of proc is exactly about that. From the point of System Programming, it contributes nothing, but it contributes a lot if you look at it from the point of App Development.
