Re: Converting Hashes to Objects

[Corion]

If you're not tied to creating objects, I found locking hashes quite good to prevent typos:

use Hash::Util 'lock_keys';
my $hash = h2o { foo => "bar", x => "y" }, qw/ more keys /;

lock_keys $hash;

print $hash->{ foo }, "\n";  # prints "bar"
$hash->{ x } = "z";  # setter

$hash->{batman} = 'secret'; # dies

Definitely, and I actually use that a fair amount, and Hash::Util's functions were part of the inspiration for this. The advantage of this module is that it saves you two characters ;-) (they're a little slower to type on a German keyboard too...) One of the disadvantages is that method calls don't interpolate into strings.

(Hmmm, maybe I could to add a -lock option to additionally lock the hashref's keys, so the hash can be used safely in both ways... Update: Done!)

Thank you very much for the inspiration, I just released v0.06 that locks the hash's keyset by default :-)
