<pre>I love the new implicit copy constructor warning, but it seems it is
overzealous about what constitutes a user-declared destructor. For example
class EnumIterator
{
public:
EnumIterator() = default;
~EnumIterator() = default;
};
static void E()
{
EnumIterator a;
EnumIterator b;
b = a;
}
Results in the error:
error: definition of implicit copy assignment operator for 'EnumIterator' is
deprecated because it has a user-declared destructor [-Werror,-Wdeprecated]
~EnumIterator() = default;
^
note: implicit copy assignment operator for 'EnumIterator' first required here
b = a;
But clearly, despite technically being user-declared, it is user-decalred to be
the default, which I would think is functionally equivalent to the non-user
declared case.</pre>
