Or even "MArray2<Complex>::stack(a)", sorry the fault was only in the
e-mail not in what I implemented.. Thinking about the problem is
probably that the template needs to be instantiated somewhere, though I
thought the call to the templated method should have done that itself..
I think I see in any case why these functions haven't been templated in
the past :-)
