There have been substantial changes in this version, it is now a much
more complete language, and the source code is in much better condition.
It still has far to go, however.
Comments?

You implementation of operations as classes is a nice idea but a perfect speed
killer, too.
As for the source code, to every header of the file at least add one or two
lines that explain what the code in this files does. Without it one has to
read the source code or look for the function names the guess which purpose
some file has as part of the whole.
I don't have time to compile it or take a closer look, sorry!

Wups...the stuff at the top of the page happened when I replaced the
HTML headers, not sure how the </body> disappeared.

I'm really not sure what the best way to do them is, I plan to do some
tests. I basically see three possible ways:
1: A struct of an integer value and whatever needed data, a big enum,
and a giant switch (which alpha 1 and 2 used, it got pretty messy).
2: A struct of a function pointer and data.
3: A class with a virtual function.
However, I don't really see how a virtual function would be considerably
slower than function pointers. And it seems faster than it was before,
though I have made too many changes to accurately judge. Previous
versions used a giant switch statement, which was difficult to work with.
I'll probably keep the use of objects to create the operations, even if
they just get converted to something else. The constructors give a
convenient way of giving the needed information to the operation.

I've still got a lot of work to do on documentation...

Same place,
http://homepage.mac.com/chrishuff/csdl/csdl.html
It is finally getting to the point that it is a useful language...
I've added ++, --, and == operators (the behavior is the same as that in
C), and tested the new loops pretty thoroughly, C-style do...while() and
for() loops work.
I've also added a way to merge member objects into the owner object,
check out the "delegate" feature. This basically lets you have multiple
"parents" for an object to inherit from.
I've also added a graph object, and povray.csdl now produces indented
output. (sorry Ken... ;-)

Oops, found and fixed an error in the multiplication/division code, and
fixed the problem with scalar-vector expressions apparently evaluating
to scalars. Maybe I'll make an alpha 4.1 release tomorrow, if anyone
shows any interest.

Your reply comes a little late...
I'll just release an alpha 5 this weekend, it isn't really worth it to
release alpha 4.1 now and another one in a few days.
