[Microbit-Python] Max recursion depth limit

[Christopher Arndt]

Hi all,

participating in the micro:bit world tour I currently have a micro:bit
at home and am experimenting with MIDI output, which generally works
very well (using a minimal circuit with just two resistors and a MID
output socket).

However, as my scripts got more complex, I encountered "maximum
recursion depth exceeded" errors, for example:

    Traceback (most recent call last):
      File "__main__", line 125, in <module>
      File "__main__", line 102, in play
      File "__main__", line 96, in play
      File "__main__", line 75, in playstep
      File "__main__", line 20, in note_on
      File "__main__", line 18, in channel_message
      File "__main__", line 14, in send
    RuntimeError: maximum recursion depth exceeded

Is the Python call stack really limited to only that few levels? Does it
have a fixed depth or does it depend on the type and size of objects
used as function params?
