As
Corion said, you probably don't want to do that. You don't give any details of how you want to use these hashes, so it is difficult code that is useful. If you wanted an array of hashes from the array of numbers that you gave:
my @a = (1, 2, 3, 4);
my @hashes;
for my $num (@a) {
push @hashes,{}
}
You access the hashes, let's say the second hash with a key called 'key', like this:
$hashes[1]{key} = 'some value';
print "$hashes[1]{key}\n";
Much more elegant that creating dynamic variables.
