cases should be disallowed or at least discouraged</td>

<tr class="even print">
<td class="print-category">Description</td>
<td colspan="5" class="print">In a testsuite in the LTE context, there
was a select statement over a (very large) enumerated type where some
cases (probably wrongly due to copy-paste or some other editorial
reason) used the same enumerated values in multiple cases.<br />
<br />
According to the current semantics of the select statement, this is not
forbidden and in effect leads only to dead code, i.e. the later cases of
the same value are never reached. Since it is not disallowed, it also
doesn't seem to be checked by the available tools up till now, even
though this would clearly benefit the user.<br />
<br />
Therefore, it is proposed to forbid/discourage unambiguous overlapping
of cases, i.e. a later case shall not use only the same expressions that
earlier cases already covered.<br />
<br />
Of course, since it is allowed to use templates in select statements,
the overlapping-property can not in all cases be easily (or at all) be
determined. It should be up to the tool how much effort should be put
into this analysis beyond checking for the same syntactic expressions
(which is trivial).<br />
<br />
For backward compatibility reasons, we should simply strongly discourage
such definite overlapping, so that tools shall be allowed to treat that
as an error, if they find a definite overlap (and otherwise ignore it as
before).</td>
