(I nearly accidentally deleted your name from the top of the email but
remembered just in time!)

Am I right in thinking that our current benchmark suite is not very

I see we have <numpy>/benchmarks - does that cover most or all of the
cases you want to test?

Maybe that in itself could be an orthogonal piece of work?  I hesitate
to ask - but can we (I) help in that?
