I like your idea of having a default that can be overridden.

The code above is actually Scheme (which Arc is implemented in). Getting and setting table values in Arc is much less clunky.

Yeah, I can tell it's Scheme because of #f used for false, instead of NIL.

If it's possible to pass an optional parameter to an Arc-style hash-table lookup (one where you use the table name as the function), than that would also allow overriding a default to NIL, because the 'or in that Scheme code would return NIL rather than evaluating the hash-table-get for the original default.
