I've recently come to realize that the 'one-size-fits-all' mega-snippets on marzer.github.io/tomlplusplus aren't necessarily useful for everyone, and I should break them up into smaller sub-examples. I'd be totally happy to accept help with this, though that may be wishful thinking!

From reddit post:

Is there any way to automatically (RAII-style) de-register event Handlers, similar to what EventCollector does in gelldur/Eventbus?

This seems like a good idea and would be relatively easy to do.
