On a more general scale, it seems like it might be a reasonable spot for an
actual new case-block-specific keyword? I can't imagine it would be an
insurmountable task to do something like make the literal word "nothing"
(followed by a semicolon) act as "sugar" in the context of case blocks for
what a lone semicolon normally does.

For example:

type TSomeEnum = (A, B, C, D);

case BlahBlah() of
  A: DoThingForA();
  B: DoThingForB();
  C: nothing;
  D: DoThingForD();
