Is there an API that DrRacket tools can use to show tooltips, that does

For TR:
* Exception handling changed to be safe. This may break existing
programs that rely on unsafe behavior.
* Exports from the GUI and framework libraries have types, and can be
used transparently from typed programs.
* Casts and predicates are supported in typed regions.

That sounds good to me.
One concern, though: it looks like recreating old releases requires that
all the participating repos (1) still exist, (2) have the same
name/location, and (3) still have the release tags. I'm not too worried
about (1) and (3), but I could see (2) happening if, e.g., a packa

With the latest from git on Debian 32 bit, I get `#t' for all four.

On a more general note, do we really need inexact integers?
The behavior of `integer?' is confusing, and I don't see especially
compelling reasons to keep it this way. The subject comes up every

Here's a proposal:

In a recent email, Eli mentioned that the `meta' collect was not meant
for distribution.
However, `meta/contrib' contains scripts that are of general interest,
and IMO should be distributed. For example, we've had users trying to
find the bash completion script, only to realize that it wasn't in t
This looks useful to me.

I like this one. I really like the idea of combining lambda with
parentheses. The unbalanced paren bothers me a bit though.
