auto foo()
    in {}
    body { return 0; }
void main() {
    foo();
}


DMD 2.048 prints:
test.d(2): no identifier for declarator foo
test.d(2): semicolon expected, not 'in'
test.d(2): Declaration expected, not 'in'
test.d(3): unrecognized declaration

I also hit this bug but on Linux and I suppose it fails on all platforms.

My test code is

auto foo()
body { // does not compile if body is specified
    return 0;
}

void main() {}

It fails with latest dmd (v2.052)
test.d(2): function declaration without return type. (Note that constructors
are always named 'this')
test.d(2): no identifier for declarator foo()

This bug makes using contracts and auto return type impossible. Maybe it's importance should therefore be increased.

Maybe issue 5867 is the same as this.

DMD v2.053 on Linux do not accept the following code:

----------
auto F1() {return 0;} // OK

int F2() body {return 0;} // OK

auto F3() body {return 0;} // ERROR: function declaration without return
type...

void main()
{
   F1();
   F2();
   F3();
}
