IIUC, boost::ref in a signiture will automatically deduce a reference
from the parameter, so pass-by-value and pass-by-reference still look
the same at the call site.

in_out is designed to use pass-by-reference similar to boost ref, but it
forces explicit acknowledgement at the call site, it specifically to not
extract a reference from a value.
