It has an integrated dependency injection system, inspired by Angular 2. It requires pre-registering the "injectables" (like all the other dependency injection systems I know), so, it adds to the verbosity and code repetition.

As the parameters are described with TypeScript types (similar to Python type hints), editor support is quite good.

you should first check whether the call succeeded before checking the error
result. For example:

	n, err := C.setenv(key, value, 1)
	if n != 0 {
		// we know the call failed, so it is now valid to use err
		return err
	}

Calling C function pointers is currently not supported, however you can
declare Go variables which hold C function pointers and pass them
