Suppose one creates a type definition like:
TStatus = (stInit, stProcessing, stFininished)

and uses it in:
case Status of
stInit: ....;
stProcessing: ....;
stFininished: ....;

If, in a new version, a new status is introduced, one would have to verify that all relative case statements are updated with the new status. It would help a lot, if Delphi would supply some help with it, for example with a 'scan for incomplete case statements' command, or a compiler warning if a case statement with a enumerated type does not include all possible case labels, or an else clause.
