I already did, although briefly.  I think its even in the upstream repository 
(?).

Yes, but I'm trying to get a little bit behind that.  For example there
is a common idiom of

1. gather overlays in a vector
2. sort by prioriy
3. determine the effective value of some property at some position

So there should be a function answering question No. 3 without necessarily going
through steps 1 and 2 .
