Can you really argue that depending on this makes things easier
to read, I don't think so! And it is quite error prone. It is
all too easy to write
if asdfasdf > oiuyoiuyoiuy or asdfadsfadsf < oiuoiuyoiuyoiuy
and not junk
and be confused by the indentation. To me this was one of the
sound decisions in Ada. The cost to the writer, extra parens.
The benefit to the writer, avoiding bugs like the above. The
benefit to the reader is clear.
