When compiling flexi-streams 1.0.3, SBCL signals a number of style warnings:

STYLE-WARNING: Implicitly creating new generic function READ-SEQUENCE*. STYLE-WARNING: Implicitly creating new generic function CHECK-IF-OPEN. STYLE-WARNING: Implicitly creating new generic function TRANSFORM-OCTET. ...

Would there be objections to introducing explicit definitions for these generic functions?

The attached patch introduces a new file "generics.lisp" that contains defgenerics for the implicitly defined generics and includes that file in the asdf definition for SBCL.

In my opinion it would be nicer to put the defgenerics next to the definitions of the methods. I can provide a patch for that as well.

Best regards
