hmm, you're right, I just personally prefer having related variables
collected in one data structure (whenever possible) like a list (or
enum in this case) rather than defining each independently as a const
variable. On the other hand, I understand that you'd prefer to skip
the extra step of converting the enum to string.
hmmm ok, I'll change the enum and send a new version soon.
