A more-useful uri_to_assoc

[eluser]xwero[/eluser]
I wonder if it wouldn't be better to alter the (slash_)segment and (slash_)rsegment methods to accept a string which is the key of the key-value pair?

Code:

function segment($n, $no_result = FALSE)
{
    if(is_string($n) && ($key = array_search($n,$this->segments)) !== false)
    {
       $n = $key+1;
    }
    
    return ( ! isset($this->segments[$n])) ? $no_result : $this->segments[$n];
}

The _get_vars method of the extended class does some strange things to end up with the same value as the default value of the ®uri_to_assoc method? Maybe i'm not awake enough to understand it.
