[BUG] no match for operator<< and const cpp2::nonesuch_ #961
Description
After pulling in 510eae8:
main: () = {
a: std::any = 1;
std::cout << a as int << std::endl;
std::cout << a as int << std::endl;
}
transpiles to
#define CPP2_IMPORT_STD Yes
#include "cpp2util.h"
auto main() -> int;
auto main() -> int{
std::any a {1};
std::cout << cpp2::as_(a) << std::endl;
std::cout << cpp2::as_(std::move(a)) << std::endl;
}
but does not compile
anys.cpp:10:13: error: no match for ‘operator<<’ (operand types are ‘std::ostream’ {aka ‘std::basic_ostream’} and ‘const cpp2::nonesuch_’)

I can confirm that the transpiler output changed to:
#define CPP2_IMPORT_STD Yes #include "cpp2util.h" auto main() -> int; auto main() -> int{ std::any a {1}; std::cout << cpp2::impl::as_(a) << std::endl; std::cout << cpp2::impl::as_(cpp2::move(a)) << std::endl; }but trying to compile still gives:

Ah, my bad. I'll see what I can do to fix it.

Thanks! This should now be fixed with the above commit, please check.
