Hello, I continue my work with Typed/Racket and Racket, and I now have another problem, with the same error. I try to use in untyped racket a typed async-channel of type Any, and I'm not able to use the higher-order value from this channel. Here is an example code that show this problem : ```

Unfortunatly, not. I'm building a framework were the user will send data over the async-channel, so I didn't know the type in advance, and cannot specify more the async-channel... On 04/20/2018 02:50 PM, Sam Tobin-Hochstadt wrote: Can you give a more specific type to what you send on the chann

Can you move the communication into an untyped submodule and use external type specs to move the values into the typed world? We could learn from this what’s missing from Typed Racket. > On Apr 20, 2018, at 10:14 AM, mailoo wrote: > > Unfortunatly, not. > I'm building a framework were the

In that case, which side is not typed? If the user side isn't typed, then you can _read_ things of type `Any` from the channel just fine. Sam On Fri, Apr 20, 2018 at 10:14 AM, mailoo wrote: > Unfortunatly, not. > I'm building a framework were the user will send data over the > async-channel, so

The untyped world will read and write... The typed world surround this actions (async-channel-put and async-channel-get) by other things. I want my framework Typed and using it untyped, but it seems hard to manage! But beside, thank you for looking at my problem! On 04/20/2018 05:41 PM, Sam To

When looked as a whole, the new racketcon website looks cool. But when you are zoomed in (like I and many other blind/low-vision users frequently are), it looks something like this: Which honestly looks like something is broken with the website. Also, it completely kills screen readers. Here i

Yeah, those fancy things are an accessibility nightmare. When I zoom in in FireFox the line breaks are fine, but between 110% and 200% zoom factor the text actually gets smaller when zooming in, and beyond 200% it gets larger again. As for screen readers, I am no ARIA expert, but from what I (t
