--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> ---
I lost two hours of my life last night because of this error:
vt.C:276:15: error: conversion from 'std::tuple<int, double,
std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >
>' to non-scalar type 'tuple<int, float, std::__cxx11::basic_string<char,
std::char_traits<char>, std::allocator<char> > >' requested
276 | make_tuple(17, 2.718281828, std::string("Fun"));
| ~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I might have notice sooner that it's "std::tuple" vs "tuple" if I hadn't been
double- and triple-checking the std::__cxx11::basic_string noise :-(
Without default template args:
vt.C:276:15: error: conversion from 'std::tuple<int, double,
std::__cxx11::basic_string<char> >' to non-scalar type 'tuple<int, float,
std::__cxx11::basic_string<char> >' requested
276 | make_tuple(17, 2.718281828, std::string("Fun"));
| ~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
And with std::__cxx11::basic_string replaced with just std::string:
vt.C:276:15: error: conversion from 'std::tuple<int, double, std::string>' to
non-scalar type 'tuple<int, float, std::string>' requested
276 | make_tuple(17, 2.718281828, std::string("Fun"));
| ~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
(I've reported PR 105672 to improve this specific case, as the real problem is
orthogonal to the request for improving std::__cxx11::basic_string output.)
