Hello, I have an hash like this: 

my %hash1 = (
        key1 => 'relative_path',
        key2 => {
                key21 => 'another_relative_path',
                key22 => '/an_absolute_path',
                key23 => 'relative_path',
        },
        key3 => '',
        key4 => 4
);

I want to create a new hash that is equal to %hash1, apart from some specific values that I want to check if these are absolute or relative paths. If they are relative paths I want to add some $home_path, For example I would want to check only these values: 
$hash1{key1}
$hash1{key2}{key22}
$hash1{key2}{key23}

So to obtain: 
my %hash2 = (
        key1 => "$home_path/relative_path",
        key2 => {
                key21 => 'another_relative_path',
                key22 => '/an_absolute_path',
                key23 => "$home_path/relative_path",
        },
        key3 => '',
        key4 => 4
);

It would be useful if I can define the list of values to check with some simple syntax, for example 
@list = ('key1','key2:key22','key2:key23');

Thanks for any suggestion!
