Well, that's a matter of personal taste.  Garlic is good on
*everything*.

For many things this is true (and I use function lookup tables
frequently).  However it doesn't as conveniently cover all use cases
that switch/case does (as it requires a function definition for each
item).  While it's also true that if/elif/else can be used instead for
these other cases, I personally find switch/case far cleaner looking
(when there are more than five or six conditions to test).

Also, I'd be reluctant to claim that the dictionary lookup is cleaner
(it looks more cluttered to my eye), but rather, more flexible (items
can be dynamically added to the list).

Regards,
Cliff
