S02 states that there is no ".length" method on Str's (or for cumulative element length of Arrays); you have to ask explicitly for the units you want to count . But then it goes on to define the StrPos and StrLen types, which are unit-agnostic. So why not have a .length that returns a StrLen? I envison some method or sub wanting to have access to the length of a string, without necessarily having the string itself available, in a context where the caller wouldn't know what level of Unicode abstraction to use.
