Custom validation error messages per rule

[quote author="xwero" date="1219061286"]Why make it so difficult? If you want different messages for the same rule why not create aliases for the rule.
MY_Validation.php

Code:

function password($str)
{
   return $this->required($str);
}

And add the password line to the language/idiom/validation.php file.

Personally i like to add the originating rule to the function to make it easier later to see which rule is aliased, even in the language file. This makes password in the snippet required_password.[/quote]

But it isn't just different error messages per rule, it is different error messages when their are two validation rules on one field...
