Perfect example, Simon. How in the world do you "copy" DTML Document class?
It doesn't show up in the Product Management Control Panel. Yet I know that
to change its meta-type, I'm going to have to get into the Control Panel, no?

I have learned that debugging is a borderline nightmare. I've read
everything I can get my hands on and still it seems Zope debugging is
primitive to non-existent. I'm sort of surprised that's the case given the
relative maturity of the product.

Sigh. That's sort of where I am. I miss the power and simplicity of
Smalltalk. I could even *choose* Smalltalk because I'm in complete charge
of those decisions. But when the finished app has to work over the
Internet, requires a remote object store, and needs to be deliverable in
small enough chunks that dial-up users can use it, Smalltalk disappears as
an option. I spent a LONG time looking at options before settling on Zope
and I'm loath to give up on it. But programming in this environment is
reminiscent of some of the labor-of-love languages and tools I used over
the years that were always a bit short of commercial success and viability.
The absence of an IDE for Zope makes the experience of building Zope apps
so cumbersome that I feel confident much of the time that all of the time
I'm saving coding because of the nice OO environment and the cool built-in
ZODB is being lost in the procedural and mechanical details of getting even
relatively simple product-type stuff to work.
Periodically, I go into a fit of pique and I search to see if there's
anything else out there I could use that would be better. There is, but not
within the affordable range of my finances, system infrastructure, and time
for learning. I guess I shouldn't be surprised but it is starting to make
me believe that I should simply abandon the idea of creating real-world
Web-based apps and services and just go back into my writing hole, leaving
software development to younger, more agile and more patient minds.
