in reply to Re: Tree Structure Challenge

How should I run your solution to get the result for the following?
```'Zoo'->diff( 'Zoo'->new(qw( Dog Fox Wolf )),
'Zoo'->new(qw( Fox )));

Not saying that I'm getting

```Can't use an undefined value as an ARRAY reference at ./zoo.pl line 40
+.
```(\$q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord
}map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+\$1,++print+eval\$q,q,a,

What should the result look like?

Not saying that I'm getting ...

Huh?

```dd( deeef( qw/ Dog Fox Wolf / ) );
__END__
(
["Dog", "Canine", "Mammal"],
["Fox", "Canine", "Mammal"],
["Wolf", "Canine", "Mammal"],
)
What should the result look like?
```( [],
[ 'Dog', 'Wolf' ]
)

Huh?
I know how to run your code. It doesn't follow the specification: you haven't implemented a static method.
```(\$q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord
}map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+\$1,++print+eval\$q,q,a,

I know how to run your code.

Its right there in the code

It doesn't follow the specification: you haven't implemented a static method.

I didn't implement a static method because its just extra indirection -- the spec contains enough indirection on its own, it doesn't benefit from extra confusion

Speaking of which, you say it should return

``` ( [],
[ 'Dog', 'Wolf' ]
)

That is kind of a surprise compared to your original sample data and sample ooutput ... as it stands my "solution" isn't there yet
