Need Help??

I was aware of this:

my $indent = ' 'x5;
# Yields '     '
[download]

But didn't realize I could also do this:

my @list = (1)x5;
# Yields (1,1,1,1,1)
[download]

So I can stop doing this:

  @placeholders = map {'?'} @columns;
[download]

And start doing this:

  @placeholders = ('?')x @columns;
[download]
