This changes the environment only. It does not change the function 
called on the``dg()'-request---and the function called does not depend 
on the environment.

But including a dependence on the environment may not change the 
output, because the compiler may instruct the executable to memoize the 
output.

Hint: casting is equivalent to exclaiming: "I know what I am doing. 
Therefore: shut up compiler!"
