In Noexcept, it is not correct to always use try_, for the same reason you
don't always use try with exception handling. That is only used if you want
to _handle_ errors, not just check for errors; see the second Q&A here:
https://zajo.github.io/boost-noexcept/#qanda.

Error checking with Noexcept depends on your choice of return type. For
example, if your return type is T *, you'd check for 0, if your return type
is shared_ptr<T> or optional<T>, you'd check using the conversion to bool.
