Of course, since Perl allows in-place modification of arrays, you can implement quicksort much more efficiently than that in Perl, but that way is much more cool-looking.

Incidentally, there is only one set of comparison operators in Haskell. To deal with the fact that Haskell is a strictly-typed language, there are multiple implementations of the same operator for different argument types. This is done throught the type classes that FoxtrotUniform mentioned. The determination of which implementation to use in a given expression is made at compile-time, which is both very powerful and very annoying. Getting Haskell programs to compile is rather difficult, but once they do they stand a pretty good chance of working the first time.
