If `from()' were added I'd want it done in C and managed by upstream
so it can be used in more than just the head of a script.

-- BUT now I am more in favor of adding both forms of `in' beyond the
forloop-in:

local a, b, c in some_table
local a, b, c = x, y, z in some_table

I thought it would be confusing but I really like it.
