That's not Rob's suggestion either.
I know, but as I mentioned, I use the above often, whereas I find Rob's definition not very intuitive or useful.
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.
