Generated init methods should or could check that all mandatory fields in the class have been set.

[smarie]

From #2

At the end of generated init methods, we could optionally enable validation that all mandatory fields have been set. That could be implicit or explicit. A prerequisite is to have a function able to provide this functionality on an object class (getting behind the scenes the list of fields applicable to this class).

This function could also be explicitly used by users, anywhere in their code (in an init method or elsewhere)

Note that this is not as simple as looking at the init arguments
