Just because something is lawful also doesn't mean that it is the
correct or most elegant way of doing things.  Depending on location 0
to hold a specific value isn't a very portable way of coding.  Even if
code is not intended to be ported, I think the programmer should try to
keep in mind techniques that lead to easy porting.  You never know.  I
guess still being a student I have extreme ideals (which are at times
impractical), such as if it's worth writing, it's worth writing well.
