Lexical environments can be used for reading as well. The code below
does the equivalent of "local x,y,z in t":

in t do

end

There's still a repetition but it's like that already in 5.1.

But you'd have to declare x,y,z and locals outside the lexical scope:

local x , y , z
in t do
    x , y , z = x , y , z
end

wait... does that work? I find these lexical envs confusing. (and I don't have a 5.2 on me)
