yield by itself generates invalid cpp

[Lubrsi]

For example:

function foo() {
    yield 1;
}

function main() {
    foo();
}

Generates:

#include <lib.h>
static void foo();


static void foo()
{
    using _JaktCurrentFunctionReturnType = void;
({ Optional<i64> __jakt_var_0;     {
        __jakt_var_0 = static_cast<i64>(1LL); goto __jakt_label_0;
    }
__jakt_label_0:; __jakt_var_0.release_value(); })}

ErrorOr<int> JaktMain::main(Array<String>)
{
    using _JaktCurrentFunctionReturnType = ErrorOr<int>;
    {
        foo();
    }
    return 0;
}

Which produces this:

/home/lukew/Desktop/repos/jakt/build/a.cpp:11:50: error: expected ';' after expression
__jakt_label_0:; __jakt_var_0.release_value(); })}
                                                 ^
