[Sbcl-devel] sb-simple-streams:open silently ignores unknown stream class

[Kambiz D. <da...@m-...>]

Hello,

as this is my first post, I would like to thank you for your work on
SBCL, which I've been using since some time.

Today, I was looking into sb-simple-streams for the first time, trying
to open a mmapped file with

(sb-simple-streams:open "/etc/hosts" :class 'mapped-file-simple-stream)

note the omission of the package for mapped-file-simple-stream.

Unfortunately, the call returned NIL without any hint that I was making
a mistake. A small change to the cond form in open would give clueless
people like me a heads up what the problem might be.

I have attached a patch with the change and would be happy to hear your
opinion.

Kind Regards
