My experience is that :tbnl-bivalent-streams must be added to *FEATURES*
before TBNL is _built_.

The source code seems to support this notion as the #:+/- checks will
occur at compile time.

It seems that :tbnl-bivalent-streams could be added to features
automatically for SBCL by adding :sbcl to the code block on line 309 of
specials.lisp:

 #+:sbcl

I would not worry tremendously about breaking older versions of SBCL
because 1) TBNL is already broken on older versions of SBCL and 2) most
SBCL users track pretty close to the latest release.

Cheers,
