In the section « 9.3.4.6 Functions» of the C++23 Standard there is a confusing footnote after the paragraph
«3 A type of either form is a function type.80»
«80) As indicated by syntax, cv-qualifiers are a significant component in function return types.»
 
Let’s consider a simple declaration
 
struct A
{
   void f() const {}
   void f() {}
};
 
And how is the cv-qualifier significant component of the function return types? The both functions have return type void.
 
The footnote requires a clarification. What does this footnote mean?
 
With best regards
