How can function argument declaration be introspected?

Is there a way to programmatically access the function argument validation declared in the argument block? meta.method introspection only allows to determine argument names, but I am interested in all of the validation features (dimensions, class, validation functions).

My need especially focuses on functions (not only class methods) and also on output arguments.

Hi Simon, I work with the team who works on the arguments blocks and meta information. We'd like to hear more about what you're wanting to do with the meta information. Could you please send me a message via the link on my profile?
