Is there a (clever?) way to achieve the following using a single
function call?

//does chdir

void fun(){
...
   string dir0=getcwd;  scope(exit) chdir(dir0);  chdir(dir);
...
}

//desired:
void fun(){
...
   chdir_scoped(dir);
...
}

Delegates can be used as well:

chdir_scoped!({
    chdir(dir);
});

void chdir_scoped (alias block) ()
{
    string dir0=getcwd;
    scope(exit) chdir(dir0);
    block();
)
