Re: [racket-users] Re: Is there an easy way to daemonize a thread?

Re: [racket-users] Detecting whether failure-result is used by dict-ref using chaperones?

Stepping back a little, a chaperone constructor for a datatype often needs some inside information and cooperation from the dataype implementation. For example, `chaperone-hash` has the property that you want --- the filter applied to a `hash-ref` result doesn't get used if a failure thunk produces

I am a Racket beginner trying to create my own DSL. As a long-time user of Xtext and other similar tools in the Eclipse ecosystem, I have come to Racket expecting that it would address similar concerns. At the moment, I have mixed feelings: I find the metaprogramming facilities in Racket very ef

[racket-users] Detecting whether failure-result is used by dict-ref using chaperones?

Hello, I'm working on a version of `dict/c` with chaperones, but I'm running into a surprising problem that only comes up because of the `failure-result` optional-argument to `dict-ref`. When the `failure-result` is used, I don't want the "value" contract to apply to that result. But when the
