I think it should be removed. The support for `=>' in `case' clauses is already documented in the manual. Having a /eggref/5/srfi-87 page is going to be misleading, as it would indicate that a srfi-87 egg exists. > If we do, of course I can take myself out of the credits for packaging > up SRFI-87 as there'll be no SRFI-87 egg, and take out the Version > history section, and I could put in a note that SRFI-87 is supported in > Chicken core with a link to the page you linked to above.

You could import it because you had a srfi-87 module installed on your system (probably your own egg). Regarding not being able to install it, did you call chicken-install from the directory with the sources of your egg? If you didn't, that's expected to fail, as the egg has not been added to our egg servers. > Here's a log of what I did: > > % csi > CHICKEN > (c) 2008-2020, The CHICKEN Team > (c) 2000-2007, Felix L.
