One gotcha that got me. If you're using 64-bit Ubuntu, you have to
install the 32-bit compatibility packages for the binary to work.
$ sudo apt-get install ia32-libs
will solve that little problem.

The Jaunty version does work.
I've created a script that downloads and installs the Ubuntu version
in the /opt directory, in a folder called /opt/plt-version# with a
symbolic link at /opt/plt. It also installs a desktop file so that

Thanks for that paper! That's exactly what I was looking for.
It seems that it is far from a trivial problem, which I initially thought it
was.

Hi everyone,
I'm writing a simple scheme compiler for educational purposes, and I'm
getting confused over "compile-time" versus. "run-time". If someone could
offer a simple explanation that would be greatly appreciated.
I don't understand when macros are expanded. Low-level LISP style macros in

I don't know whether planet modules can be used within Pretty Big, but I
have a case/equal? and a case/string-ci=? defined in my bzlib/base module -
feel free to try it out or take a look at it (in base.ss).

The semantics of case are a bit annoying at times. To guess as the
reason for this, I suspect it is to allow efficient implementation for
switching on numbers and the like. There is cond for

Unfortunately, you can't use "case" on strings, for somewhat esoteric
reasons:

No mistake. case uses eqv? for comparison (on the quoted thing in each clause).

The current exception handler really is determined by a continuation
mark and not by a parameter (i.e., a mark that is separate from the one
that determines the current parameterization).

It looks like you have `call-with-exception-handler' right, but not
`with-handlers'.
The exception handler installed by `with-handlers' needs to escape to
the context of the `with-handlers' form before finding whether any
handlers apply. In other words, `with-handlers' combines a prompt
