# NAME RESOLUTION
#... Command names are also always resolved by looking in the current
#namespace first. If not found there, they are searched for in every namespace on
#the current namespace's command path (which is empty by default). If not found
#there, command names are looked up in the global namespace (or, failing that,
#are processed by the unknown command.) ...
