Well, as Jonas argues on fpc-pascal, you are supposed to add useless statements
anyway, which the compiler will then 100% remove...


In all seriousness though, that is why I didn't include all integers. But enums
and small ordinals are often used as a "what is this data" tag, where it is
usually an oversight if some value is not checked.
I'm already not super happy this also applies to Char (a OS_8 ordinal), because
it makes case-based regular language parsing quite noisy.
