in thread Print a string X times?

in the statement print +('-') x $length , "\n";

the +('-') does some magic which I don't understand, could you please explain that statement..

    From perlop: Symbolic Unary Operators:

    "Unary "+" has no effect whatsoever, even on strings. It is useful syntactically for separating a function name from a parenthesized expression that would otherwise be interpreted as the complete list of function arguments."

    Try removing the + and ensure you use strictures (well, warnings anyway) and see what happens.

    True laziness is hard work
