I guess Pythoncoder is referring to the issue described in here: viewtopic.php?f=16&t=1876

The microbit adaptation seems to have a heap of 2423 bytes:

from mprun.c ( ... it/mprun.c)

// allocate the heap statically in the bss
static uint32_t heap[9692 / 4];

So I guess we are more prone to reach the limit sooner than with the other boards.

The persistent bytecode functionality described by pythoncoder at viewtopic.php?t=1776 is a little bit beyond by current level...

Would plotlist not be smaller if it were made up of tuples rather than lists?
