It breaks the behavious of case:

DoElse

As it is now, b=2 and a=False will result in no code executed.
After the patch, B=2 and a=False will result in DoElse.
Have you actually tried it? I've tested those cases and they should work.
Then in your patch, how do you distinguish between the else belonging to the
case statement and the else belonging to the if ?
When compiler hits 'end' inside 'case', it analyzes syntax tree
created for the last branch, and checks if there was semicolon before
last else or not (which is clear sign if that else is part of if
statement or case).
So this feature is inconsistent ?
Imagine I've a case like:
case Foo of
1 : DoOne;
2 : If a then DoA; else DoNotA;
3 : DoThree;
end;
Now, due to changed requirements, 1 and 3 shout do the same, so I change
the case into:
case Foo of
1,3 : DoOneAndThree;
2 : If a then DoA; else DoNotA;
end;
This will affect the meaning of 2 too, without noticing...
No thank you.
