Yes with a proper expression engine it's all redundant. I haven't
looked at Jiri's stuff in detail, but it seemed very simple-minded
and may not support all the computation needed.

Also would allow to finally replace the bogus perf stat -d frontend/backend

For stat there's no really a compelling reason to integrate
it, the usual wrappers work as well. They have the advantage that
they can be written in real programing languages, instead of trying
to invent a new one.

Expressions integrated would be mainly useful for things like
"counting perf top"
