Complete Minimal Classes

With a class expression and .{, you can also conceivably have constructor properties:

var MyClass = class extends Foo { ... ) . { /* constructor properties go here */ }

I don’t use constructor properties often, so I think it’s OK not to have them in MM classes (with the option of adding them e.g. in

The point is that there have been dozens of full-featured proposals just like yours which haven't come to consensus. Max-min was an attempt to take every controversial feature out while still remaining useful and leaving the door open for the future. It seems to me that so far this is the closest to consensus. Trying to go the other direction is probably just going in circles. Maybe I'm wrong. I know that the biggest thing holding it back is that for a couple holdouts it is too minimal and possibly competes with some of the work being done for object literal extensions. Personally, I think that if anything should be done to fix Max-min it should be in the private name area.
