problems importing srfis

May 2, 2009 at 10:04 PM
I came across an error attempting to import an srfi:

 (import (srfi :1 lists))
Unhandled exception during evaluation:
&assertion

Isn't that the correct syntax?

Hi Matt

> Isn't that the correct syntax?

Yes, that is the suggested syntax for importing SRFI for R6RS.  I have not implemented that naming scheme yet.

For now you can simply do:

(import (srfi lists))

I will put it on my TODO list.

Thanks

Hi Matt

If you download the the latest source code, you will find this working  :)
