 ##### Note
 
-Ranges are extremely common in C++ code. Typically, they are implicit and their correct use is very hard to ensure. In particular, given a pair of arguments `(p, n)` designating an array [`p`:`p+n`), it is in general impossible to know if there really are n elements to access following `*p`. `span<T>` and `span_p<T>` are simple helper classes designating a [p:q) range and a range starting with p and ending with the first element for which a predicate is true, respectively.
