Then you arguing wrong. Then you don't need validation everywhere, but
something you can call to simply confirm an enum has correct values after
reading.
It is not logical to have heaps of checks littered everywhere if the
corruption happens in a defined place (on load).
Worse, tying it to range check would then have heaps of redundant checking
everywhere, not just enums.
True. That's why I believe that Read from a (typed) file should perform
such validation - but it doesn't at the moment, as mentioned in my e-mail
in the other thread. :-(
IMHO it should not.
By declaring it as a File of Enum, you are telling the compiler that it
contains only valid enums.
