o Is there a reason this idea  was scrapped?
o Also, since load is currently the only mechanism to set the _ENV
upvalue without using the debug API, I'd like to see a generator for
compiled chunks that let you set the _ENV upvalue:
function _main (_ENV)
return function (...)
--[[ chunk ]]
While this can be done by modifying the source of Lua code, it can't
be done with precompiled bytecode. Perhaps most importantly, this
allows us to create a new closure of a compiled function without
recompiling it (or reloading the bytecode). If I want to run the same
function in different threads with different environments, I would
need to re-compile it each time to create a new closure, currently.
