This allows us to create maps that exist in the 0->n where n is small. This provides some performance boost. TODO: Make the same optimization on the Golang side, this should provide better performance there too. This reduces trace overhead by ~10% for a particularly heavy vulkan application.

Can we delete this implementation so that it won't compile if the key is non-integral (that or put some statement in here that doesn't compile with a comment)? Doesn't seem like you'd ever want this to compile...

// TODO(awoloszyn): Template tricks to move this to compile-time
is resolved. Until then we have a dynamic check, which means this will need to compile.
