I presume in PDL that gets you a 10x10 matrix of floats? In that case
you're not getting a scalar back, you're getting a matrix. That it needs to
be represented as an object is an indication of one of perl 5's
limitations. (And then the compactness would be something the object
applies to whatever data structure it builds

Right, so the question still stands--since scalars are singular things, how
(and why?) would you compact them?

So then it's not relevant to the question. :)
