a question sbcl integration

[james anderson]

good afternoon;

what was the intent with respect to the implementation for stream- 
file-position present in sbcl?
the trivial-gray-streams package definition is clear to distinguish  
symbols and the mixins file defines methods on the respective sb-gray  
symbol, but there is nothin apparent to serve to delegate from the  
trivial-gray-streams function to the sb-gray operator.

how was this intended to work?

best regards, from berlin,
