I was not thinking about static, but runtime analysis.

I didn't say anything about compiler at all, I was more thinking RTL.

Those are inheritly static. But cycles are afaik not.

If I read all the happy users on this thread, I believe this feature will be
absolutely peachy :-)

 So since then this is only needed for extreme cases, such interactivity
might be a bit too much :-)
