These are some things I found while playing with the MicroPython
(so far):

* Printing in the Python script will have the output show
  up on the console. This doesn't seem to be documented
  anywhere, but is very useful for debugging scripts.

* Bug: microbit.Image() does not take keyword arguments
  http://microbit-micropython.readthedocs.org/en/latest/image.html

* array only supports .extend() and .append()

* arrays don't support buffer protocol

* bytearray.extend() doesn't support iterators, only buffers

* bytearrays don't support slice assignment, only index
  assignment

* If you first run:
  microbit.display.animate(i, 100, stride=1, wait=False, loop=True)
  and then:
  microbit.display.animate(i, 100, stride=1)
  you get a deadlock.
  There's no way to stop the background animation.

* need an API to query the available memory on the heap; useful
  for debugging memory leaks, but also to prevent MemoryErrors
  from crashing your script

Should I open tickets for these somewhere ?

Given the limitations under which MicroPython has to operate,
some of these would likely be documentation bugs more than
anything else.
