Bug 8933 – -property switch and opDispatch for methods and properties

When the -property compiler switch is in effect, opDispatch cannot be used for both methods and properties. Currently, we can just omit the switch and things work fine. But if the behaviour of the switch becomes the norm, this issue will have to be addressed. struct Demo { @property auto opDispatch(string name, A...)(auto ref A args) {} } void main() { Demo d; d.test(1); // method call OK d.test(1,2); // ditto d.test = 4; // property setter OK d.test(1,2,3); // error, properties can only have zero, one, or two parameter } If you omit the @property attribute from the opDispatch definition, the compiler complains 'not a property d.opDispatch!("test")'. Perhaps the simplest fix would be for opDispatch to be excluded from any property rules altogether.

The -property switch was deprecated: https://github.com/dlang/dmd/blob/8b4b87f871277ac25b062b0e785044a574c2ce3e/src/dmd/mars.d#L364-L379 I don't think this is valid anymore.
