in thread Why should I use perl 5.10?
The qw() operator provides list context already. So
print ( qw(a b c) x 3 );
yields the same result as
@l = qw(a b c); print ( (@l) x 3);
which makes sense imho. An array isn't a list, but a qw() expression is.
update: as a reminder, this is from perlop:
Binary "x" is the repetition operator. In scalar context or if the left operand is not enclosed in parentheses, it returns a string consisting of the left operand repeated the number of times specified by the right operand. In list context, if the left operand is enclosed in parentheses or is a list formed by "qw/STRING/", it repeats the list. If the right operand is zero or negative, it returns an empty string or an empty list, depending on the context.
