I guess I was mistaken, and took something that Mike said the wrong way.
I appologize for that!
It was something about local ffi.new( "" ) elements not getting garbage
collected when going out of local function scope, instead retaining them
if they got returned... but I have to reread Mike's messages again.

Recent JVMs do

Someone was claiming on HN a few days ago that escape analysis is a
major win for PyPy. There was speculation that this isn't as
important for LuaJIT thanks to its representation that does not
require numbers to be boxed:

In that same thread someone claimed that you are planning to
implement escape analysis -- not sure where they got that info. :)
