[Templates] Getting keys from a hash

[Karl Dane]

I guess my example wasn't a very good one - I just wanted to demonstrate 
that I was getting _nothing_ when using the keys method. If it had 
worked as expected, then it should have returned something like 
'ARRAY(0x8a8ca58)'

I keep playing, and so far any vmethods I use on the hash don't seem to 
work.

e.g.
[% cgihash.size %] returns nothing.
But [% list = [1 .. 10] %][% list.size %] returns '10' as you'd expect.
