At the axom meeting on 1/28/2023, we discussed an alternate resolution of converting the mcodes parameter to sort_mcodes from an axom::Array to an axom::ArrayView which would avoid the copy.

Should I apply this suggestion instead of the by-reference capture?

Let's put in the by-reference change at this point, and later change to use an ArrayView.

These avoid some annoying repeated warnings from cub and thrust about the Clang version needing to be greater than 6. They're not particularly useful to us when using the XL compiler, since it's C++ implementation is sufficiently modern.

As far as I can tell, nvcc's preprocessor appears to be replacing std::runtime_error with class std::runtime_error when the code has using namespace std

The errors here and below were:

<axom>/src/thirdparty/axom/fmt/format-inl.h:127:8: error: expected expression
return class std::system_error(ec, vformat(format_str, args)); 
       ^
<axom>/src/thirdparty/axom/fmt/format-inl.h:1456:32: error: expected expression
write(std::back_inserter(out), class std::system_error(ec, message).what()); 
                               ^

Using a type alias circumvents this problem.

I'll try to create a simple reproducer (ideally outside of fmt and axom) and log an issue.

In the meantime, our fmt_smoke test should trigger this issue (and require the bugfix in this file).
