And I don't depend on Fortrannical optimizations that can break
whenever the vendor feels like it.  If I want things linked
that closely, I'll keep them close.

Some of us like the fact that arrays are passed as
pointers, and can be aliased rampantly.  It's a matter of
looking _both_ ways before stepping into the street, though
the traffic is _supposed_ to be traveling in only one
direction per lane...
