Support for global uncaught exception handler?

[daemianmack]

Hey, I'm curious if Planck allows defining a global uncaught exception handler?

e.g. in Lumo I would do something like this...

(.on js/process "uncaughtException" #(js/console.error (js/Date.) "uncaughtException" %))

@daemianmack There is no facility in Planck itself. I wonder if there is a JavaScriptCore equivalent to your example above. Failing that, I suspect we could add something somewhere to catch things. Does this tend to occur with callbacks or core.async?

Not currently in pursuit of any particular use-case; at the moment I'm making do with a top-level try/catch but was curious if there was another option.

@daemianmack Cool. A while back, I made some improvements to ensure that if you run a script, and it fails by throwing, then Planck will itself report the exception. Perhaps this covers the main concern. I'd be curious to know if you actually need your top-level try / catch and if Planck's inherent reporting works in your case.

In this case we want to do some cleanup as part of the catch, so it needs to be custom. Definitely appreciate the auto-throw though. :)
