Solely for QoL development (like adding ternary to Go :)) Ternary util.

creates a http.Handler with my own function type (I prefer making handlers or controllers to return concrete object/struct if success and return error if anything goes wrong, complying with go's error handling way) go don't have default parameters, and since for my use case only C operations will return a diff status code for success cases (I am not trying to rebuild a whole new full-fledged net framework :))), will use variadic parameters and determine if a diff code should be used the bad thing is there's ntg stopping me from providing more :((.

if setup environment variables in system alrd, pass in empty string and will attempt to load environment variables from the system.

returns every elements that are in `ori` but not in `compared`.

creates the grpc simulation service client and calls callback with the client.

faster access than os.Getenv.

Either type is a workaround for union types in go, eg.
