<div>
<pre>Short-circuiting in a requires-clause normally works, but if any overload of
`&&`/`||` is visible, the corresponding operator stops short-circuiting.
Example for `||`:
struct Dummy {};
// Uncommenting this breaks the code:
// bool operator||(Dummy, Dummy) {return true;}
template <typename T>
struct A
{
static constexpr bool value = T::value;
};
template <typename T>
void foo() requires (sizeof(T) == 1) || A<T>::value {}
int main()
{
foo<char>();
}</pre>
