I didn't closely follow this thread so maybe it was answered already,
but did you consider using an upvalue for the environment?
in <identifier> do ... end
This lets you swap environments by assigning to <identifier>. This
also covers an example of Mark Hamburg:
local c = Class()
in c do ... end
could become
in c do ... c = Class() end
