I suppose some very trivial examples could be better written as a
conditional expression, but I believe it's generally better to use method
dispatch than "manually" dispatching. At the very least, the code might
possibly perform better using the built-in method dispatch mechanism (or
not).
Certainly it seems cleaner to me to simply add/remove methods to change the
logic rather than modify some hairy expression. Furthermore, using method
dispatch allows you to modify the logic in multiple modules or libraries.
Really the only concern, I think, is that you need good tools to make it
easy to see all the methods if you're maintaining the code, but this is
essentially true for any code.
