Stack allocation for structs with heap references


#1

I just want to point out that this optimization should also help Query.jl a lot, I also iterate like mad over small immutables that can hold references to heap allocated stuff. I just tried to find an issue or PR that gives the latest status/efforts/plans on that front but didn’t really find something. I’d be quite interested in learning about the current plans on this, any pointer would be most welcome.


Julia motivation: why weren't Numpy, Scipy, Numba, good enough?
#2

#3

This is definitely something I am looking forward to as well, but it requires someone with a deep understanding of how Julia GC is working and requires some non trivial work (e.g. stack scanning). AFAIK nobody is currently actively working on it.
