Another big feature needed by APIs is data validation, making sure that the data is valid, given certain parameters. For example, that some field is an `int`, and not some random string. This is especially useful for incoming data.

Without a data validation system, you would have to do all the checks by hand, in code.

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

Il ne peut pas très bien gérer les modèles imbriqués. Ainsi, si le corps JSON de la requête est un objet JSON comportant des champs internes qui sont à leur tour des objets JSON imbriqués, il ne peut pas être correctement documenté et validé.
