Re: [Sbcl-devel] [Sbcl-commits] master: Add some type-derivers

[Alastair B. <ala...@gm...>]

Speaking of, almost anything in the gray stream interface which is declared
(in SBCL) to return BOOLEAN probably shouldn't be
(STREAM-DEFINITION-BY-USER says "true or false", and the CLHS for the
corresponding CL functions says "generalized boolean"). With certain
policies, this leads to typechecks being emitted on the calling side,
causing strange errors.
