Hi Lars,

...
but when you use them as type-constraints the actual type being constrained will be
inserted automatically as the first template parameter.
...
template <typename T> requires
std::convertible_to<T, int>
void foo(T t) {}
template <std::convertible_to<int> T>
void foo(T t) {}
void foo(std::convertible_to<int> auto t) {}
...
Many, many thanks. This was the bit of information I lacked.
Best wishes,
jeanette
