Document that fmt::arg takes a non-owning reference, even if that reference is to a temporary. As such, users should make sure the lifetime of the reference lasts as long as the named argument.

@mikelui, could you please review the updated CONTIBUTING document, particularly the part about licensing, and let me know if you agree with it being applied to your contributions to {fmt}? The library is likely to be relicensed (#1073) so I'm collecting approval from all earlier contributors. Thanks! |
