Rob is wrong - might_have and has_many produce identical SQL. The difference is how the
result is interpreted. has_many is a multi-type accessor, so when you call ->doodads
you get a resultset object from which 0 or more objects can be retrieved. If instead
you use might_have, calling the accessor (which you'll probably call->doodad, instead
of doodads) will either return a *row* object, or undef. If the sql contains more than
1 result, the first one is turned into an object, and the rest of the results is
discarded with a loud warning.
