FUNCTIONS

    all_defined
         $bool = all_defined( @values )
 
        Return FALSE if some of values in array are undefined

    hf (hash filter)
         @values_by_filtered_keys = hf( $precompiled_regex, %hash_array )
         %hash_array_of_filtered_keys = %{hf( $precompiled_regex, %hash_array )}

        EXAMPLE:

         %hash   = (key_ax=>'val_ax', key_ay=>'val_ay', key_bx=>'val_bx', key_by=>'val_by');
         @values = hf(qr/\w+/,%hash);
         %values = %{hf(qr/\w+/,%hash)};
 
    set_hmv
         set_hmv( \%hash, $key, $val, [ $force_single ] );

        set hash multi-value - for multiple appearances of same key are
        values stored as arrayref rather than direct value. Usefull when
        parsing cooikes or url with multiple param names.

        $force_single set to 1 drops/replaces previously stored values with
        the $val for the $key specified.

        SEE ALSO get_hmv

    get_hmv
         get_hmv( \%hash, $key, [ $index ] );

        get hash multi-value - counterpart for set_hmv.

        TIP: use *$index = -1* to get last value or other negative values to
        index from end of values array. (Same way as with common perl array)
