Thanks for all the praise, but please don’t forget that the current code in the pull request is more of a proof-of-concept and it still needs quite a bit of work (error checking, handling corner cases, etc.).
Could you give some more detail on what you mean by this? Do you mean the reference by name to m & h in the line
ina = Equations('ina = gnabar*m**3*h*(ENa-v) : amp') + m + h
?
Oh, and if you have an opinion on the Equations vs. EquationTemplate question (see PR), please let me know!
