It's an old thread but just in case someone is looking for the answer Julia has

Hello All,
Due to licensing concerns with using GNU's libreadline library for the
readline collection, we are switching the library to libedit. This should
not affect most people as libedit is included with OS X and most Linux
distributions (and Windows never had libreadline to begin with).
The r
To offer another speculative solution, perhaps there could be a variant of
Typed Racket structs that are opaque to untyped Racket. If only Typed Racket
code is capable of constructing these objects, the types of their contents
needn't be checked as they pass between typed and untyped code.
On F
Your feedback and some more thinking about it has convinced me to not
make the backward-incompatible change.
I'm still going to make Plot objects (though not in 6.2). They'll just
be created by different functions.

Submit a bug report, because that number is obviously false. (Or you've

The problem is that first-order polymorphic contracts are O(n) in the

I'm delighted to offer both. Here's a particularly pathological test case:

Using a typed/racket/no-check variant of the tr-pfds package makes my

Actual Performance Bottlenecks (and Workarounds)
(1) Plot's sending of `snip%` instances from untyped to typed code made
them so slow that they were unresponsive. I got around it by making
helper functions to create the snips, and inserting their

Ah, so that explains the only glitch I'd wondered about: Seeing
someone reply to a message I hadn't yet got, but which shows up a day
or two later.
What I'd much prefer at the moment over speculative solutions are reports of
actual performance bottlenecks. -- Matthias
