	No real suggestions for a fix, but the implementation of the method 
	STREAM-WRITE-CHAR on the class T seems arguable: calling
	(clim:stream-write-char (clos:make-instance 'foo) #\x)
	runs into an infinte loop on the symbolics.

    Genera's stream implementation predates the rest of the stream
    implementations in the world by several years.  I hesitate to call it
    a stream "system", because it really just accreted slowly over the
    years and does not implement any reliable protocol.  With the advent
    of CLIM, Genera uses *four* different object systems to implement
    streams:  structures, Old Flavor-like streams, New Flavor streams,
    and CLOS-based streams.

    What this means in real money is that CLIM has no choice but to write
    some stream methods on the class T, because there is no other place to
    hang them.  What Moon proposed is probably the right fix: default
    methods shouldn't cause STREAMP to return T.

Yeah, but this has to be fixed in the CLOS WHICH-OPERATIONS
mechanism, not in CLIM proper.
