I didn't think it was that important a point

Lisp isn't as big and slow as you might think, optimising Lisp compilers can
outpace pretty much anything but straight C & assembly

LOL, most PERL programmers I've come across are clueless and undisciplined

Perhaps they do, but some languages are more implicitly readable and
maintainable than others no matter how good your programmers are. Haskell is
a good example, it is a pure functional language, much of the code can be
proved to be correct via mathematical methods, it's more expressive than PERL
yet more consistent and for most generic problems (e.g not something a
language might specialise in like cat in PERL) I can write shorter, more
readable and easier to maintain code for you than in another language.
qSort  = 
qSort (x:xs) = qSort [y | y <- xs, y < x] ++
qSort [y | y <- xs, y >= x]
Fibonacci Sequence (as a self recursive, infinite list):
fib = 1:1:zipWith(+) fib (tail fib)
Sieve of Eratosthenes prime number generator
prime = sieve [2..]
where sieve (x:xs) = x : sieve [ y | y <- xs, y `mod` x /= 0 ]
