How can one generate a Tuple in MGrammar?

Question

I mean a real "MGraph Object Model Tuple".

Answer 1

Why doesn't anybody answer by saying "One cannot"?

I am beginning to suspect that one can.

Answer 2

One cannot. :)

MGrammar can only produce lists and collections, as things stand right now. Closing this gap is part of the larger effort of bringing MGraph, MGrammar, and MSchema into full alignment.

(Sorry, I'd previously called lists "sequences".)

Answer 3

Very clear.

Thank you.
