Here is what I am going to commit.

It's nice to see that this kind of "devirtualization" optimization
actually works now. In this way the patch could really have an impact
on OOP code performance.

Would be interesting to see if we get a measurable speed-up in
real-world code, like e.g. Salvatore's PSBLAS.

Cheers,
Janus
