Arc has a lot of bottlenecks when speed matters, but I never felt floats were one of them...

I've used Arc professionally twice. Once as a web interface to an rsync system (http://my-arc-stuff.blogspot.com/2008/02/i-needed-web-app-fo...), the other one as a database for our local library (basic stuff : which book do we own, who borrowed it, ...)

These are real apps. I must admit Arc is really great (even as it is now) for these small, basic but usually time-consuming webapps. It doesn't prevent me for writing a compiler for Arc :) (which is itself written in Arc and is actually the biggest piece of code I've written in this language).

In ac.scm, add :

  (xdef 'cos 'cos)
  (xdef 'sin 'sin)
  (xdef 'exp 'exp)

And you're done.

I think that should be

  (xdef 'cos cos)

etc.

yep, you're right. sorry.

You mean, pg's interest ? Sure, he doesn't seem to be very involved anymore... :)

And note the first release has no problem with Unicode :)

Yes, it's veeeery far from being usable. But, hey, it's only been started 6 or 7 days ago...

Please update us when you have something reasonably stable.
