Thanks!

I guess string constants are retained even if they are not being referenced by anything?

Yes, all constant strings which appear in script are interned. But again, we made change that expressions consisting of just strings (which covers docstrings) are discarded. Submitting a bug for this issue will make sure it's revisited and not forgotten.

Before I submit any more bugs I should probably learn to build the project and flash the board and all that good stuff - it probably is fixed as you say, but I'm still running the version of micropython that came on my board and I haven't tried the unix version or anything.

I flashed my board and it looks like that issue with the docstrings is at least partially resolved - space is allocated for them on import, but the garbage collector removes them when it runs. Seems adequate to me? I will log a bug if you disagree.

Hmm, I'd guess parser could free such strings explicitly, saving gc from extra work, so I'd suggest filing a bug.

This means that we should include docstrings in micropython modules, right?

You can, and you should not be concerned that they may waste memory when run on MicroPython (they won't).
