Well, it’s rather simple, but maybe there is already a built-in function to do calculate this? natural_length(s) = s[end]-s[begin] natural_length((1,10)) natural_length((1:10)) It annoying to copy-paste this snippet which is not large enough to bother putting it into a package.

[image] mkitti: This does not work for all iterators. Even last(a) - first(a) seems wrong to me for a non-sorted iterator. A more general solution would be to use the extrema function : diameter(itr) = -(reverse(extrema(itr))...) which is equivalent to the more verbose (but more readable) …

Is there a built-in function for the natural length of a segment represented by an iterator?
