To concatenate string, actually any object to a string, I'd prefer #& as in

'the result is ' & (3 + 4)

(I know it's trivial to implement but still one has to be careful when to
introduce new binary oprations as they're more difficult to learn than
unary or keyword selectors because they produce more cryptic code.
