'case of' block with changing of selection variable

[AlexTP]

Would be good if changing of 'case' selector will not be allowed:

Code: Pascal  [Select][+][-]

1. program pp;
2. var
3.   n: word;
4. begin
5.   n:= 3;
6.   case n of
7.     1:
8.       begin
9.         n:= 2;
10.         writeln(n);
11.       end;
12.     2:
13.       begin
14.         n:= 1;
15.         writeln(n);
16.       end;
17.     3:
18.       begin
19.         writeln(n);
20.       end;
21.   end;
22. end.
23.

Hi
Hmmmm.... I depend a lot on changeable case selectors in my various simple state-machines ~ oldschool parsers.
I would very much like them to stay the way they are!

Currently a case should always contain an else (even if empty)to avoid warnings. Real warnings, not hints.
Jonas did not correct that after I pointed that out. I mean flatly refused to correct that.
Maybe that is your issue too... Then add to my bug report.
That "feature" was only added for ISO compliance and makes no sense in other modes.

It does not break code, though.

Feel free to decline this post, developers. It's only a micro idea.
