The official way of coding that is: 
${$hash_ref}{key} = ${$array_ref}[1];

You may leave of the braces if the content of the block is a simple variable. Perhaps you find that obfuscated, but that's actually the same rule as the first (optional) argument of print. The file handle is passed as a block, and taken as the result, but if the block is a simple variable, you may leave off the braces. If that isn't obfuscated, why is the code I presented obfuscated? Or is it that you aren't used to it, and call anything you aren't used to obfuscated?

If you want to take a slice of a hash or an array, and all you have is a reference to it, how do you do it without being "obfuscated"? I write it as: 

    @$hash_ref{$key1, $key2, $key3};

which follows naturally from accessing a single value: 
    $$hash_ref{$key1};

[download]
But 
    @hash_ref->{$key1, $key2, $key3};

[download]
doesn't work and nor does 
    $hash_ref->{$key1, $key2, $key3};

[download]

And no, my code isn't littered with 

    &{do {... sub {...}}};
