Here are a couple of pointers to save you some typing. Firstly, you can use the quotewords operator, qw{ ... }, when initialising your array of names.

my @names = qw{ Tom Mary Nat Luke };

It is more idiomatic to use a Perl-style loop rather than a C-style loop and also create your sub-hash in one go. (Note that $#array is the highest subscript whereas the array itself in scalar context, scalar @array, returns the number of elements).

foreach my $idx ( 0 .. $#names ) {
    $people{$names[$idx]} = {
       number => $idx,
       numbx2 => $idx * 2,
       };
}

Note that you can also iterate directly over the names if you so desire, though it's not applicable in the code you give.

foreach my $name ( @names ) {
    $people{$name} = { this => q{that} };
}

I hope this is useful.
