Reading http://www.galois.com/methods.php, you come across this
justification for using a higher-level programming language:

"All programming languages suffer from a semantic gap: once the
developer has worked out how to solve a problem, they have to
translate that solution into the concrete syntax of the programming
language. In traditional languages, such as C, C++, and Java, the
semantic gap is large, and the translation is error-prone and
time-consuming. In comparison, functional languages, such as Haskell,
ML, and Caml, allow developers to express their ideas relatively
directly. The rest of the translation is handled by the compiler,
and is governed by strict, mathematical principles. By removing the
ad-hoc, error-prone, time-consuming translation step, functional
languages enable developers to produce correct code in a fraction
of the time."

Not that it will impress macho programmers, but perhaps it can
be used in order to try to explain things to people who have
to deal with programmers, and wonder why software development
is such a beast to manage.
