case-expr is the expression appearing in a SELECT CASE statement (k in
the test), while here the problem is in a CASE statement, dealing with
So I think C830 doesn't apply here. But you can rely on F08:C832 saying:
"For a given case-construct, each case-value shall be of the same
type as case-expr"
The type of case-expr is only checked in resolve_select, so the check
for the value-expr's should probably happen there as well.
