That's not Rob's suggestion either. Rob's suggestion is an operator which concats two substrings with exactly one space between them, without stripping leading or trailing whitespace of the result. Examples: a = "\nHeading:" b = "Result\n\n" a & b would give "\nHeading: Result\n\n" s = " my hovercraft\n" t = " is full of eels\n" s & t would give " my hovercraft is full of eels\n" I find the concept is very easy to understand: "concat with exactly one space between the operands". But I must admit I'm struggling to think of cases where I would use it. I like the look of the & operator for concatenation, so I want to like this proposal. But I think I will need to see real world code to understand when it would be useful. -- Steve
