A variant of this principle as advocated by some posters in this
newsgroup is

"Never implement things, even if they are simple to implement.  When
these things are needed, instead of spending the minutes it takes to
implement them (or adapt an existing implementation), better spend
many hours arguing why they are not needed.

If you absolutely cannot avoid implementing something, a
special-purpose solution that fails on corner cases is to be preferred
to a general-purpose solution even if the implementation complexity is
the same.  This vindicates your argument that the general-purpose
thing is not needed, and anyway, we all know that general-purpose
solutions are bad.

Building two, or five special-purpose things is better than having one
general-purpose thing, because each special-purpose thing is simpler;
and if it's not, it's at least more special-purpose."

However, Forth itself is the anti-thesis of this approach.  Instead of
writing each program special-purpose in machine language, Chuck Moore
built a huge hook: the dictionary and FIND.
