--- Comment #1 from rhalbersma <rhalbersma at gmail dot com> --- I just became aware of [depr.array.comp] in N4861 "Equality and relational comparisons (7.6.10, 7.6.9) between two operands of array type are deprecated." This is very surprising to say the least and disqualifies default op= for any class containing a C-array. But in any case, should such code generate a warning message? And this bug be closed?
