Hi list,

I'm trying to understand how to interact with Java functions which 
return arrays, e.g. double[][] or int[].

When I call a function which returns an int[] or double[][] they display 
as numbers within [ ... ] square brackets.  I can extract their length 
and elements, e.g. using (x 0) etc where x is the array.

What kind of object are these in the Scheme universe?  array? vector? 
and the uniform vector tests return #f.

I tried an idea I found under uniform vectors, to try to make a uniform 
vector share the Java array, but I only get type errors.

I would like to convert these Java arrays into a Scheme list or vector, 
which should be a simple function to write.  But is there a 
function/trick like that already?
