Whalesong appears to be tickling a bug in Typed Racket under Racket
5.2.  I apologize for this; I should have caught this when Racket 5.2
came out.  I'll try to be better at tracking with Racket's subsequent
releases and make sure this doesn't happen again.

I just released Whalesong 1.13 to let it work cleanly with the
upcoming 5.2.1.  If you grab a pre-release Racket and try it with
Whalesong 1.13, do you see a similar error?

I'm in the middle of dissertation writing, so unfortunately I won't be
able to work on getting #lang racket/base working until I'm done with
the darn thing... :)  But I'll be back to work on this during the

The #lang line does work, though with a restriction.  See the slightly
ridiculous examples:


The restriction is that a language's runtime bindings currently needs
to bottom out to modules that are written in (planet
dyoo/whalesong/lang/base) or a very small subset of '#%kernel.  You
can still access full  Racket for the compile-time macros, though, as
the hello-bf example demonstrates.
