Such values are not actually local variables, so there was no scripted 
name.

For example, to evaluate:

  local e = (a + b) * (c + d)

Lua (like any other language) has to effectively do:

  local e do
  local t1 = a + b
  local t2 = c + d
  e = t1 + t2
  end

t1 and t2 are reported as (temporary), which they indeed are.
