Maybe an issue with the op precedence? I'll check it out

Great. As you may have seen I've made some changes today and gotten a few of the NeuroML files working.

Regarding this bug, it may be good to add unit tests on expression parsing like there are for unit string checking: https://github.com/LEMS/pylems/blob/master/lems/test/test_units.py

Rechecked and this is still an issue...
