That definitely looks like a bug. Can you file one either using the
bug report tool in the menus or at bugs.racket-lang.org.
No you cannot define a predicate like that, because you cannot tell a
functions type with a first order check. But you can use cast, so

Hi all,
In the Racket 5.3.4, I defined the following predicate

and later, I tried using as follow:
>(A? 'a)
But I have the following error:

In the program below, I never receive on-subwindow-char calls (or any
of the other calls). (Except when they correspond to mouse events like
the wheel up events.) Is there some other way that I'm supposed to get
key events from a top level window? I know I can create a canvas, but

One thing that seems to happen fairly consistently is that I end up waiting
a lot on the background syntax expansion. Sometimes Racket recovers.

Slightly off-topic, and probably preaching to the choir, but:
It's definitely worthwhile setting up two-factor authentication for
your Google account.
After you do so, you can generate per-application passwords (as
Matthias mentioned). For example you'd ask Google to generate one for

I have just installed 5.3.4 on Windows 8. But, of course, since it uses the
"Start" Page and tiles, there isn't an issue with choosing a Start Button.
I got tiles for DrRacket, GRacket, Racket and Docs. (Which is nothing
compared to the 100 or so tiles I got from Cygwin!)
