#2ELI5. How is maphash different from just using map?
I am surely missing something. I thought the builtin map used hashing too?

The maphash package from the blog post provides routines that call into Go's runtime to hash arbitrary types.
The maphash package in the standard library (hash/maphash) provides routines that hash string and []byte.
The builtin map type is a hash table.

Maphash is a library for computing hashes of arbitrary types in Go, not a map data structure.

I get wanting to solve a problem, but at what point into fighting the language, to accomplish something simple, do you take a step back and just pick a better one?

Such as?

#7So the reinvented wheel (golang) is now starting to miss / reinvent Java's .hashCode() or an alternative to it?

My choices would be:
- Elixir
- Rust
- Clojure
- Crystal
In that order.

I'm hoping Kotlin + GraalVM Native Image can fit the niche of golang.

I hate Go, but there is no solid alternative for what I do. Documentation quality. Compiler performance. Library support. Easy packaging. Easy language. Consistent cross platform tooling. Easy concurrency. Good for web apps and CLI tools. Reasonably refactorable.
Note I say easy and not good, or simple.
Rust, Haskell, JavaScript, all get caught up on some aspect or another for me.
