The latest draft of SRFI 121 is now posted to
<http://www.ccil.org/~cowan/temp/srfi-121.html>.  The implementation
resides at <http://www.ccil.org/~cowan/temp/generators.tar.gz>.
Please pull both files to srfi.schemers.org.

The following changes were made since the last draft:

Add back make-iota-generator to provide a finite generator with a fixed
count and optional start and step.

Flushed grepeat*, gsubgenerators, ggroup-by operators as unnecessary.

Flushed all syntax extensions.

Modified the implementation to conform to the SRFI.

Completely rewrote the test file as a Chicken test egg application.
