See perlop about .. in scalar context, the flip-flop operator.

    Thanks Aristotle, you have me shaking my head. A great lesson indeed. I read the perlop and believe you were referring to:

    In scalar context, ``..'' returns a boolean value. The operator is bistable, like a flip-flop, and emulates the line-range (comma) operator of sed, awk, and various editors. Each ``..'' operator maintains its own boolean state. It is false as long as its left operand is false. Once the left operand is true, the range operator stays true until the right operand is true, AFTER which the range operator becomes false again.

    Thanks again.
