This wrong D2 program:

void main() {
    int foo = 1;
    int foo = 1;
}


Produces a good error message (dmd 2.048):
test.d(3): Error: declaration test.main.foo is already defined


But this similar wrong program:

void main() {
    int foo = 1;
    int foo -= 1;
}


Produces two wrong error messages:
test.d(3): semicolon expected, not '-='
test.d(3): found '-=' instead of statement


I'd like this second situation to generate the same error as before.
