code, which seems to work pretty well, but I figured Racket would be
pretty heavy for a mobile device.

It worked ok, but I never used it to make apps.
Ive not tried, but I suspect the real work is making a racket
library/interface for the ui stuff.

Yep. I was very surprised to find no scheme that compiled to native
code and had gtk bindings. Work is being done on the chicken-qt
bindings, at the least, but for the time being I've fallen back on
vala.

Typed Racket can do compile-time dispatch:
http://docs.racket-lang.org/ts-guide/optimization.html
(the documentation is more complete in the nightly builds)
We do compile-time dispatch using types. We're also looking into
making it possible for users to define their own type-based
optimizations.
In the docs for canvas%

the limits for function init-auto-scrollbars
are given as

you probably are better off adding this directly to drracket. You

Actually, after reading more, letrec* also demands (again page 36, top

letrec* is not like let* at all, really, which kin
And yet again I am an idiot, as you did not refer to the value of a
binding that *follows* it. Instead you are referring to a value that
precedes it, which should be allowed. Thankfully that does restore my
mental model of the starred lets, though, so apart from several
embarrassing emails on this
It has been a while but I believe the r6 formal model covers this point.

I do not often use rnrs, for I prefer racket. But sometimes people ask me
