Gray stream compatibility

[ehuelsmann]

The last thing holding us back from being fully Gray stream compatible, is that TYPEP should return T for any fundamental-stream derived instance when tested against 'STREAM or (find-class 'STREAM).

[ehuelsmann]

Due to other priorities, this didn't make it into 0.20, I'm affraid.

Because I want DEFINE-METHOD-COMBINATION done in the near future too (like in 0.21, for example), I'm setting a more realistic goal for this ticket.

[ehuelsmann]

0.23 is getting crowded, but 0.22 has been released.

In getting Hunchentoot to work, I have committed a fair amount of rework to the Gray Streams code (c.f. r13255 and r13272).

At this point the problem described in this ticket is at least solved, but it is unknown when this exactly happened

It is not expected that there are no further errors in using classes derived from GRAY-STREAMS:FUNDAMENTAL-STREAM as the current code base was not systematically audited with this end in mind. Additional problems should be filed in new issues.
