I personally disagree with that one because it's just fluff, considering
that "nothing" is equivalent to "{ nothing }" - usually a keyword or an
intrinsic should actually do something.

Whenever I come across a section of code in my own projects where

confusion with the syntax on first viewing; e.g:
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();
end;
