Ah yes, thank you — I was so close.
I think probably it should handle newlines & paren sha

Next example.
In Racket:

'((f 5) (e 9) (c 12) (b 13) (d 16) (a 45))
In Typed Racket I couldn't get a version using #:key to type-check. Pulling
second into a comparison function works:

This seems like something that has been done before, but I'm not sure where to
look for it:
I need something like `syntax->datum` — call it `syntax->source` — that uses
the source locations and 'paren-shape property of the syntax to reconstitute
the source with its whitespace (I suppose comment

Yea, workaround that works for me is to fake a Tab key-event:
(define/override (on-activate activated?)
(super on-activate activated?)
(send this on-subwindow-char this (new key-event% [key-code #\tab]))
)

Just updated to 6.5 on Ubuntu, but I can't get a control to focus. My issue is
similar to http://lists.racket-lang.org/users/archive/2011-May/045317.html, I
have a dialog with a choice% in it, and no matter when or how I (send choice

Ah, okay. Well maybe try the Haskell or OCaml versions of the 99 problems?

At that point I was asking whether Sam (or others) recommended another set
of problems more conducive to learning Typed Racket than the 99 Lisp
Problems which Sam said were a tricky place to start.

I guess you already solved this one, but for later it might help to avoid
macros.
