Yes, it was fixed shortly after 5.1.

I second Eli on a second level.
As much as I think that syntactic simplicity helps a lot of languages,
I don't think this particular kind of simplicity is a major problem or
even worth our attention.

Does this make it into more of a #lang mixin, as was recently discussed

Here's a smaller test case for the problem/bug. Since this doesn't
call any of the framework/drracket, I'm assuming it's an issue in the
GTK bindings.

I prefer this over `scut' for two reasons. (1) It makes the simple
cases simpler: you don't have to name anything. (2) It doesn't try to
handle the more complicated cases, which I think is a good thing.
Things that are implicit should either always do the right thing, or
just do something simple.
If you forget how to find super-cut:

If you have an application with one (or more) occurences of `_' as
immediate subforms, then that application is rewritten into (lambda
args the-original-application).

But then this:
(map (+ 1 _) (list 1 2 3))
would turn into
(lambda (_) (map (+ 1 _) (list 1 2 3))
no?

Looks to me like it goes at the outside. So the macro plows through the terms
and when it gets to the bottom, it decides either to wrap the whole thing in a
lambda or not.

Scala has the nice feature that if you write something like this:
lst.map(_ - 1)
It automatically rewrites to a function like this:
lst.map(x => x - 1)
This makes writing some higher-order functions much easier.
Of course, it's easy to make this using a macro and `#%app'. You can

Fixed for me too, ubuntu 11.04 32bit, not using unity.
thanks a lot Robby!

In consultation with Matthew, I've pushed a change that fixes the too
small menu bar problem, at least on a VM on my laptop.
If you're seeing this problem, can you check and see if the change
fixes it for you too?
Also, if someone could try it out on a unity setup, that'd be helpful.
Thanks,
