Well, now, whose fault is that?  Interestingly, the ideal way has actually
been seriously suggested...some number of years back, it was suggested in a
paper by Harlan Mills that, essentially, bugs are little more than an
unnecessary annoyance:

	It is an old myth that programming must be an error prone, cut-
	and-try process of frustration and anxiety.  The new reality is
	that you can learn to consistently write programs which are correct
	_ab_initio_, and prove to be error free in their debugging and
	use.

(I carefully checked the above paragraph for accurate transcription from
the original paper.  I leave it as an exercise for the interested reader to
find the grammatical errors in the paragraph [four, by my count] and draw
any appropriate conclusions about the validity of Mills' premises.)
