so global doesn't affect dofile statements at all? so when i do:
a=123
dofile('blah.lua')
do
   global in T
   a=12
   dofile('blah.lua')
end

where blah.lua is the following:
print(a)

then this example would print out:
123
123

?
Really? Interesting. so i can't use global for sandboxes in which dofile 
would be allowed?

But i still think the following:
The beauty in lua lies in the simplicity which still provides 
uncomplicated and  powerful ways of doing things.
This global statement somehow doesn't fit. it really looks like an 
complex and complicated beast albeit the "simple" syntax.
