Is there any way to error the current lua thread within a peripheral?

Whenever I use CCLights, I may put a value in wrong. The problem is that I need a way to error the current lua thread. It would be great to use IComputerAccess to error the lua thread, but browsing the code yields no results. It would be a great feature for later use by all peripherals.

throw new Exception("Oh noes, we has error!");

Thanks Cloudy!

Wouldn't that error the entire game and crash it? Which would be very bad for a server (having the entire server crash because one user inputed a wrong value into a computer).
You could queue an error event (hopefully the user would see it).

Not if you are within IPeripheral.call(). The lua machine catches the exception and propangates it as lua error.

I you are outside it, (eg in the minecraft update loop), this doesn't work of course, but who would try to launch a lua error from there anyway?

I wouldn't have suggested it had that been the case.
