If I read Jens correctly then no anagrams should produce a variable as the result
(vartype 'Empty' Ubound = -1), and I have a score of 477
(so near and yet so far [Frown] ).
If on the other hand no anagrams can produce an empty array
(vartype = Variant[] with Ubound = 0, Result[0] = Empty)
then I can get 468.

So Lonkero still rules!
