The ability to apply the usual arithmetic conversions

[[expr.arith.conv]] on operands where one is of enumeration type and the
|
| 5 |
+
other is of a different enumeration type or a floating-point type is

deprecated.

[*Note 1*: Three-way comparisons [[expr.spaceship]] between such

operands are ill-formed. — *end note*]
