描述

It would be nice if there were usage examples for sync.Map, but there are not currently any.

  • Can keys be ordinary values like strings, or should they be custom types, a la context.WithValue?
  • Should I always store a pointer to a value, or can I store a value like a string? If the former how should I do it?
