           Summary: [TDPL] -property fails to give an error when a
                    property function is called with parens

This code

struct R42
{
    @property int front() @safe const pure nothrow
    {
        return 42;
    }


    @property bool empty() @safe const pure nothrow
    {
        return false;
    }

    void popFront() @safe pure nothrow
    {
    }
}

void main()
{
    R42 r;
    auto e = r.empty();
}


shouldn't compile, since empty is a property and therefore must not compile
with parens per strict property enforcement as described in TDPL. _Not_ calling
popFront with parens _does_ result in an error with -property, but calling
either of the property functions _with_ parens doesn't. So -property seems to
be doing half of its job but not all of it. With -property, @property functions
should never be callable with parens, and non- at property functions should never
be callable without them.
