Errors are thrown unless explicitly caught. The error messages come
from different sources: Java, Kawa Scheme, an SMTP server or database
server. Errors thrown result in an HTML page that shows the message,
provides a stack trace (trimmed thanks to a suggestion from Jonathan
Bachrach), and links to an on-line user-maintained database of error
causes, as of the latest release.

would likely lead to a static vs dynamic typing thread, which I'd just
as soon avoid.

BRL first. It's unlikely that I'll have another opportunity to write
something so significant. I feel like I was in the right place at the

Now is the time to play with it. The latest release makes it friendlier
