Ah, but note the difference

import sin, cos from math  =>  local sin, cos = math.sin, math.cos

the idea is to get away from globals.  Now this kind of thing can be
done with macros or whatnot, but can't be done with table magic.

steve d.

Even more generic:

  local a,b,c from t

being equivalent to

  local a,b,c = t.a, t.b, t.c

Then the import can be written as

local sin, cos from require 'math'

But I not competent to assess the impact on the Lua grammar and implementation..
