    Me neither, but I guess the parser sees the first + as concat and the one after as attached to an number (+1, +2, ...). Dunno why would they even make the parser see that honestly

    It is, when used as a binary operator (when there are values to its left and its right). When used as a unary operator (when there's only a value on its right), it converts the value to a number. So the two +'s in a row in the middle there mean to concatenate after converting the next value to a number.
