    bar;

fails to execute do


void foo()
{
    void bar() { foo; }
    switch
        case: bar; do return;

    bar;
}

does work... yet there is no difference except the scope exit.

In my code it is if do is never executed...

I used it to avoid having to write bar twice or use a flag but 
it's not working... I see no reason why it should not work. 
scope(exit) is suppose to execute the block at the end of the 
function call, right?

No, a scope guard executes at the end of the scope. The spec[1] 
has a
few examples (with output).
