No, there is no built-in checked conversion from integer to arbitrary

Very good :)
Are there any disadvantages of the enum-AS operator that prevents its
introduction?
Someone else could already have code that overloads the AS-operator in
this way, and such a change would break this (you cannot overload
operators with a built-in meaning). I would be in favour of a new
intrinsic.
If I am not mistaken, the AS operator cannot be overloaded - so no chance
to break legacy code here.
Because
1.) you agreed that a built-in checked conversion from integer to arbitrary
enumeration type is wanted and
2.) the AS-operator cannot be overloaded and thus the only argument against
enum support for AS is not valid
I introduced the AS operator for enumerators in

Nice idea, Ondrej :)
