Hi Jordan,
I actually thought about adding a "file" method on Dispatch::Source that (in
cases where you passed in an IO object instead of an file descriptor), would
return that object. Of course it would return nothing in other cases, but
maybe that's OK. Still not sure what to call it -- any suggestions?
Alternatively, we could only add that method to a subclass of Source, so it
only existed when valid. If we did that, we should probably do the same for
the "merge" method on custom sources - but having a subclass with only a single
method seems lame. Maybe implement it in the superclass, but raise an
exception if called for an invalid type?
