Maybe you want a templating system instead? sprintf is the simplest one, and it could be used in your case as follows:

$foo = "hello";
my $x = "$foo%s";
my $output = sprintf $x, $y; # replaces "%s" with $y
print $output;

There are many, many more templating systems, with varying easy of use and complexity. I recommend looking at simple string substitution first.
