Hey guys, I just wrote this tiny piece of code

 #!/usr/bin/perl
use warnings;
use strict;

my @array=(10,20,30,40);
print: "Before: @array \n";
for(@array){$_*=2;}
print"After: @array\n";

And I'm getting an error:Useless use of string in void context at line 6. And only the second print is actually being printed. It's probably something right in front of my eyes but I just can't seem to figure it out!
