Agreed that Lua's scoping is well implemented, but ...

If you wrap the do/end sequence around each instance of the table  
insertion, then you're doing a lot of typing to avoid a lot of other  
typing. As my Grandpa would say, "That's an expensive way to save  
money." ;-)

If you use a local variable throughout the function scope, then not  
only are you doing a lot of extra typing, but you may also have to  
scan quite a bit of code above to find the real meaning of "t".
