I think you are going in the whole wrong direction. Coordinated arrays is not a good idea for starters. See if you can follow how/why this works and go from there

use strict; use warnings; 
my @sets; 
push @sets,{name=>'Country',api=>'get_country()'}; 
push @sets,{name=>'State'  ,api=>'get_state()'}; 
push @sets,{name=>'fake'   ,api=>'get_fake()'}; 


my %subs; 
$subs{'get_country()'}=\&get_country; 
$subs{'get_state()'}  =\&get_state; 

for my $set (@sets) { 
  my $vname=$set->{name}; 
  my $api  =$set->{api}; 
  my $call=$subs{$api}; 
  my $res; 
  if (defined $call) {$res=&$call;} 
  $set->{res}=$res;
  }  

use Data::Dumper; 
print Dumper (\@sets); 
exit; 
sub get_country{ 
  return 'USA'; 
  } 
sub get_state{ 
  return 'FL'; 
  }
