gg (Generic Generics)

A Go library for the generic types that should be in the standard library, but aren’t. Currently, this includes:

• an Option type similar to the one in Rust, and
• a library for defining refinement types.

I may additional types like Result, Either or Pair if:

• there is a compelling usecase for myself, and
• an API can be built that is ergonomic in practice (this is the biggest reason why Result might never happen).
