Re: Using Kawa extensions in R7RS libraries

[ElÃas Alonso G.-Cornejo <eliasagc at gmail dot com>]

The patch works correctly but raises another issue: (future ...) and
(runnable ...) are not included in (kawa base). I don't know if they
should be included, but if I require kawa/lib/thread.scm with (import
thread), any attempt to call (future ...) will show the following
message:

warning - no declaration seen for lambda

And fail. I fixed it by adding (import (scheme base)) at the top of
kawa/lib/thread.scm but I'm not sure if that's the best way to do it.

Thanks, I appreciate the directions. I've tried to read kawa's source
code before, but didn't know where to begin. kawa/standard/Scheme.java
looks like a good starting point :)
