Passing array of doubles to COM object?

[Mark Hammond]

This definately _should_ work.  VB _may_ pass it as an array of
byref doubles tho?

Can you run makepy over the object?  If so, it definately should
work from there.

In the meantime, I will add arrays of doubles to the COM test
suite (specifically, to the VB test interfaces)

Mark.
