  How would one implement QT-like signals and slots in Nimrod?

  Recent work has given me cause to use QT for some GUI designing, and the concept of signals and slots intrigue me. Alas, C++ requires a code generator, MOC, to support such techniques. Could Nimrod do better, and implement them natively?

  Preferably, minimal work (or none at all!) would be needed to allow arbitrary procedures to notify connected procedures.

  I have no idea about QT's signals, only that they recently gained type safety, but you may want to explore this article for implementation details. From the outside signals look quite similar to Cocoa's target-action pattern, which has a swift implementation here. Depending what you need that might be close enough and swift seems to be eerily similar to Nimrod so maybe that example helps.

  Usually all these things are hacks around a missing closure construct. Maybe QT's signals are different, I don't know.
