I was thinking about this in EcoBase, is that repo mothballed for now?

[mkborregaard]

No not at all mothballed but EcoBase just contains abstract types and functions on them - no implementation. A constructor needs the concrete implementation of the type, thus I thought it should go here.

Everything suffers a bit from me being a bit out of circulation as I'm writing a brand new 7-week MSc course starting in 13 days.

[kescobo]

Oh I see - that makes sense.

And I didn't mean to impugn your efforts! I understand 💯% I love teaching, but it's a ton of work.

This should use the new Tables interface.
