Additional notes (July, 2024)
The words in question were removed by P0595R2 (std::is_constant_evaluated()), adopted in November, 2018.
[ Resolved by P0595R2, adopted in November, 2018. ]
Similar to the concern of issue 2166, the requirement of 7.7 [expr.const] bullet 2.7.1 for
a non-volatile glvalue of integral or enumeration type that refers to a complete non-volatile const object with a preceding initialization, initialized with a constant expression, or
does not specify the point at which the determination of “preceding initialization” is made: is it at the point at which the reference to the variable appears lexically, or is it the point at which the outermost constant evaluation occurs? There is implementation divergence on this point.
