The suggestion was to use it in place of implicit string concatenation, which occurs only between string _literals_:

What is that? One thing that works in a way for literals and in another way for expressions? Sorry, but there is onlye one word for this: Insanity!
One of the things I love about Python is that a "thing" can be used in the same ways whether it's from a literal, a variable/name lookup, a function return value, a class member, an instance member, etc, etc, etc. (Sometimes this requires strange magic, like member function calling, but you still have the principle that "a=foo.bar(quux)" and "_=foo.bar; a=_(quux)" do the same thing.) So anything that makes str.str mean something weird gets a -1 from me. The proposals involving ellipsis have at least the virtue that it's clearly a syntactic element and not an operator, but I suspect the syntax will be more problematic than useful. If it looks like an operator, it should BE an operator. ChrisA
