<div>
<pre>enum A
{
B,
C [[maybe_unused]]
};
void f(A a)
{
switch (a)
{
case B: break;
}
}
Results into:
<source>:9:13: warning: enumeration value 'C' not handled in switch [-Wswitch]
switch (a)
^
[[maybe_unused]] is allowed to be placed at this location and the only use case
I could come up with, does not work.
