What would you say the right thing is?
Well, intuitively I would say that converting an Array of Character instances (say 5 instances) using "asString" would give me a String of size 5. Also, "Character space asString" does NOT give me 'Character space' but actually ' '. Maybe its just me, but I'd rather not have SequenceableCollection >> asString mean "If I contain only elements which may represent characters, return a string containing those, if not, return my printString"
Having a fallback on printString is of course fine, in Object. But... well, I haven't thought *deeply* on this, but a sequencable collection of Characters should IMHO be able to produce a String regards, Göran
And it is, using either collection as: String, or String withAll: collection In both cases you then explicitly specify that this collection will contain only elements which can be converted to a string, rather than have a later reader of the code have to question "hmmm, does the use of asString here mean he'll be using the collections printString, or the string with its elements?"
