It's a lot more complicated than simply destructing them at the end of a 
function. You have to define what happens for conditionally executed expressions 
|| && ?:, what happens at the end of a statement, what happens at a }, what 
happens to for statement initializers, etc., for each statement type.

You cannot declare locals in conditionally compiled expressions. So it isn't as 
simple as that.
