gollark: Also, as well as that, how it just special-cases stuff instead of implementing reusable solutions.
gollark: e.g. no map function existing or even being possible means that you have *readable* code with a for loop, but it's harder to understand *why that's there* and *what it's for*.
gollark: The main problem I have with it is that it conflates readability (you can see what the code is doing at a low level) with comprehensibility (you know what and why it's doing at a higher one).
gollark: Are you being serious?
gollark: ~~Go is Not Good~~
