It seems, as tomerarnon mentioned, a + in the beginning of a line in Julia does not represent a continuation of the line before. See:

It took at least two hours for me to find this problem: x = a + really \* long + + (and + complex) / expression + - that \* (spans - several) + lines \* of / code Can you spot the error? The problem is that the expression terminates after the third line because I forgot to hang a trailing + sign there. The fourth line evaluates without error but doesn’t do anything…

Parentheses (or + at the end of the line) allows Julia to recognize the multiline code.
