I have been working this semester translating some useful numerical
code from Java to RB... mainly because I thought it would make me
more aware of how I work and what I can do to make it better... plus
it will wind up giving me another language to do AI work in... that

From Java, I am used to thinking about external libraries of code as
classes. The idea is neat, straightforward, and I like it. However,
since I have been using RB (mainly as a project/gui tool) I have
always thought that a module WAS an external class of sorts. Further
reading about modules, though, seems to indicate that the real goal
of a module is just a central location for a collection of methods
and properties and is not instantiable. But wait: that's just a
finalized class that inherits from Object, right?
Besides subclassing, is that the real difference. Is a module just a
class that doesn't inherit from anything and can't be instantiated or
subclasses? When would it be better to use a module than a class,
then? Are there performance issues? Anything else to be aware of?
Just throwing it out there. Thanks in advance,
dave
