My feeling has always been that the overhead of initialising a float
array, per element, is considerably less than the cost of one floating
point operation; so if you ever intend to actually use the array for
anything, the inefficiency is negligible.
On the other hand if we have unsafe_set than unsafe_create is hardly a
huge additional bloat, more a kind of natural counterpart.
