I agree that most probably the compiler would figure itself that the
value of the variable will not change, but IMHO it is good practice to
constrain the types as much as possible, as it limits the runtime error
space. Anyway, this was a minor comment ;-)

I agree, we can keep this in mind for an OctoMap2 ;-)
Have a nice day,
