thank you for that hard work you put into nodemcu!
Would it be possible to
1. add a switch so that unneeded PANICs are caught on main loop level (like accessing nil)
2. Output the stacktrace of the error like http://stm32f4.web.fc2.com/elua.html
> sin(0)
stdin:1: attempt to call global 'sin' (a nil value)
stack traceback:
stdin:1: in main chunk
[C]: ?
This would allow to find errors more easily.
Thanks,
Carsten
