Thanks Simon.
'statistics' is needed for criterion (the benchmarking tool), so yes,
I'd say it's important.
I'll add more information to the ticket later today.

I believe that the old codegen is gone altogether.
Please add to the ticket to say that it blocks compilation of a particular package (with instructions for how to reproduce). Is this an important package?
Someone should just fix the codegen! Any volunteers? Simon left some breadcrumbs and I'm sure would help.
