I would like to use scope guards but in the guard I need to get

Am I misunderstanding?
Scope guards are syntax sugar for try/catch/finally. For example,
when you write
auto f = open("foo");
scope(exit) close(f);
doSomethingWith(f);
...it gets transformed by the compiler into
auto f = open("foo");
try {
doSomethingWith(f);
} finally {
close(f);
}
I do not understand exactly what the problem is you are having,
but hopefully this lets you figure out how to solve it.
