Please do not do this. The other modes are the only ones that really need it, in
Delphi mode, nothing should break on invalid enum values anyway (if it does, it
is a compiler error).
This was just an extension I added because Sven asked for it earlier in
this thread:

You know that I agree with you on the enum topic (and the case
optimization as well). With the new IS/AS I am just trying to get a
convenient and built-in way to check for valid enum values - with
"valid" I mean "valid" as the FPC team understands it (since they do the
rules).
How the IS/AS operator will be implemented and if it will be implemented
at all and not rejected is upon the FPC developers that will finally
decide about merging it to trunk. I am quite sure they will modify the
patch before applying anyway to comply with their philosophy.
My goal is to get the best from it. If disallowing of IS/AS for enums
with holes in FPC modes is a requirement for applying the patch, I am OK
with this sacrifice.
