Hello,
I'd like to start a discussion about the standard std.signals library.

5 days passed and no one answered 😒
I'll respond to say that I don't know a lot of people who use signals
and slots. It's a very old part of Phobos, and I think a lot of people
here aren't familiar with it.
Maybe the guys who are contributing to DRuntime could answer: is that
possible to attach GC dispose event handlers to the delegate context?
I've never heard of this functionality. Looking it up, it's not used
anywhere in druntime, only from phobos, and only from this std.signals
implementation (literally a search through all code finds the function
rt_attachDisposeEvent in 2 places -- the definition, and the one usage
in std.signals).
Looking at the implementation, it depends on having an Object with a
Monitor, as the event is stored in the monitor. So you couldn't attach
it to any specific piece of memory, it HAS to be an Object.
But like I said, it's not used pretty much anywhere. So I think nobody
would miss it if you ripped it out and made it better :)
feel free to open a bug report and/or PR and get some more discussion going.
