Robert, yes, you can use (many of the dozen or so) Tcl OO extensions
with AOLserver. XOTcl is probably the most powerful choice, and
several folks here have used it with AOLserver and OpenACS - including
the XOTcl maintainer,
Gustaf Neumann.
So for someone wanting an Object-Oriented language (as opposed to
wanting a not-Tcl-language) for use with AOLserver and/or OpenACS,
XOTcl is obviously the easier approach. Python or Ruby or whatever
would, at best, require additional work integrating the second
language interpretor, adding good foreign function call interfaces,
etc. etc. Someone might want to do it, but only so that they could
program in Python, not just for OO.
As for the "last 5%" of web apps that non-OO tools like Tcl handle
poorly, I'm not sure what those are, although I'm somewhat willing to
take Jonathan's word for it that they can or do in fact exist. Hm,
Jonathan, I see that you were investigating XOTcl
back in 2002.
Did you try it? How do you like it compared to Python? And how have
you seen either one used on that "last 5%"?
