Too bad this doesn't work when opCall takes args.
IOW, "S(2)" results in
Error: constructor m.S.this () is not callable using argument types (int)
Error: constructor m.S.this is not callable because it is annotated with @disable
Error: expected 0 arguments, not 1 for non-variadic function type ref S()
Removing the disabled 'this()' makes the error go away and the right
opCall() gets called.
