For what scheme implementation are you using? And
where can I
get what you are using?
I use Matthew Flatt's mzscheme, which is part of the PLT project, see
<www.plt-scheme.org>. I run it with a two line patch to put the Boehm
GC into incremental mode.
There is a pre-release archive at <www.alphalink.com.au/~rd>. I have
used this and James McCartney's SC3 synthesis server, see
<supercollider.sf.net>, as my work environment for over a year and it is
stable, however unless there is a particular affinity for Lisp I would
recommend using James McCartney's Smalltalk dialect as a language
client.
