<div>
<pre>In the following minimal example there is an error:
Minimal example:
#include<iostream>
int main() {
std::cout << std::endl();
return 0;
}
I found it really hard to tell the error form the generated diagnostic:
error: no matching function for call to 'endl'
std::cout << std::endl();
^~~~~~~~~
/include/libcxx/ostream:1032:1: note: candidate function template not viable:
requires single argument '__os', but no arguments were provided
endl(basic_ostream<_CharT, _Traits>& __os)
^
I think it would be better if the exact error would be spelled out again:
"object std::endl of type ___ does not have a function call operator
operator()"
before including the note, since in this case the note confused me and pointed
me in the wrong direction.</pre>
