You can call a subroutine whose name is stored in an array element (or, indeed, any scalar variable) like this:

#!/usr/bin/perl

#use strict;
use warnings;

sub test {
  print "pass\n";
}

my @subs = ('test');

$subs[0]();

However, note that I had to comment out the "use strict" in my code. This is generally a sign that you are doing something slightly dangerous. In this case you are using a technique called a "symbolic reference" which is really not recommended. The recommended way to do this is to store a reference to the subroutine instead of the subroutine's name. That looks like this:

#!/usr/bin/perl

use strict;
use warnings;

sub test {
  print "pass\n";
}

my @subs = (\&test);

$subs[0]->();

Notice that in this case we are able to uncomment "use strict".
