There is a feature similar to this in Perl, but this is considered to be a very bad idea, because it makes code utterly unmaintainable. Use arrays instead.

my $index = 0; my @array; $array[0] = "hello"; $array[1] = "world"; print "$names[0] $names[1]"; #=> "hello world"

You can also use variables for the 0 or 1: “my $index = 0; $array[$index] = "hello"

Or you could use hashes

my $index = 0; my %hash; $hash{greeting} = "hello"; $hash{name} = "world"; print "$hash{greeting} $hash{name}"; #=> "hello world"

Again, you could also use variables:

my $key = "greeting"; $hash{$key} = "hello";

Edit: properly escaped square brackets
