in reply to What I Most Recently Learned in Perl, But Should Have Already Known

I was aware of this:

my $indent = ' 'x5; # Yields ' '
But didn't realize I could also do this:
my @list = (1)x5; # Yields (1,1,1,1,1)
So I can stop doing this:
@placeholders = map {'?'} @columns;
And start doing this:
@placeholders = ('?')x @columns;
