OK. I'm confused again.

Yes but it will probably be necessary to overwrite the _each
method so
that the Enumerable knows how to iterate through your
collection. At
least this is my understanding.

There is a delicate balance between application performance
and
developer performance. I tend to lean a little more towards
developer
performance and then address any application perfromances as
they
become apparent.

With that said, I've been using prototype on several rather
large
projects in the last few months and I have yet to see a
performance
hit worth mentioning.

I think in regards 'to adding *lots* of extra stuff' to
your
application, you will see the same thing from other
libraries.
However, the namespace that they put the 'extra stuff' is
different.
Typically you are left with typing out verbose namespaces
and dealing
with less expresive code.
