I can't say I've ever heard it recommended as good practice from the
standpoint of performance in any specific language I've ever worked
with, but I have heard people suggest that you always include an
explicit default case in any kind of branching logic. It does seem
useless to say
default: // do nothing
break;
in a switch block, but I imagine the reasoning behind it is so that
anyone who reads your code can see that you actually thought about
what should/would happen if none of the other conditions were true
rather than ignoring those conditions.
