No, he objects for the same reason I am - a matrix being singular is
not a particularly exceptional situation, and whether an
implementation considers a matrix singular will depend in some cases
on the exact algorithm and FP implementation being used.  This is,
thus, a *terrible* example of a place to throw an exception, as
authors won't expect it, and it'll vary between platforms for no
important reason.
