A deep dive on how Go generics are implemented, with monomorphisation of call sites with primitive types for performance: https://eli.thegreenplace.net/2022/faster-sorting-with-go-generics/
The Go proposals call this 'stenciling', but I've not heard that term before. AFAICT it's monomorphisation.

I've heard of 'blub languages', where you don't realise that other languages have better abstractions until you've experienced them.
I think the same thing happens with individual features. I've seen several C++ folks miss variadic generics in Rust, but I've not written enough C++ to feel it.
It's interesting to see the "why not Rust?" discussions around the TypeScript news that they're using Go. It shows that Rust has reached a level of maturity that it's a default for some users.
Go does seem to be in a sweet spot for AOT languages with GC though.
An ad hoc, informally-specified, bug-ridden, slow implementation of half of a text adventure game -- or as I like to call it, a compiler.
