then I went a step to far, and it is plain and simple a simple type.

type matrix33=array[1..3,1..3] of float;


You seem not to specify the element type in Lady Byron's language. Is that
the special part?

But that is only possible using 
- Dynamic vars
- interpreters
- Only types with the same size are allowed (e.g. only integers etc)


So what am I missing here?
