I've just published draft #2 of SRFI 146.  It was submitted
by Marc Nieper-Wißkirchen, author of the SRFI.

<http://srfi.schemers.org/srfi-146/>

Here's the diff:

<https://github.com/scheme-requests-for-implementation/srfi-146/pull/1>

Here are Marc's comments on the draft:

  Major changes:

  - Sample implementation added.
  - Many fixes (mostly thanks to Chaw's comments).
  - Two new namespaces (srfi 146 ordered) and (srfi 146 hash)
    depending on the underlying implementation.

Regards,

SRFI Editor
