A few others have already given you good advice, but here's
a quick-and-dirty thing that you may or may not find
relevant or useful:
function myObj.update()
local someVal, xPos = myObj.someVal, myObj.xPos -- Short names
--some code
someVal = xPos * 10
--remaining code
myObj.someVal, myObj.xPos = someVal, xPos -- Reassignment
-- to long names -- wouldn't even be necessary if
-- someVal and xPos themselves happened to be tables
-- whose elements you were messing with.
end
