digitalmars.D - Re: Semantics of toString

 To put this statement into perspective, I would be most appreciative of D NG
 responding with their own idea(s) of what the semantics of "toString" are (or
should be)
 in a language agnostic ideology.
 If there are more than, say, two or three different views on the said
semantics then my
 "ill-definition" assertion is surely correct.
 If there are no replies on this matter, then guess I'm left concludeless.
 Just thinking in the language round-up that this is (just another) one of the
 we should address as a community.
 So what does "toString" mean to you?

Two things: 1) Primarily for debugging purposes. It's very convenient. 2) As a default behavior in a few cases. For instance, if a listbox widget hasn't been given a view that knows how to render objects of type Foo, it can default to rendering the results of toString.
