As I said, notorious and often cited both for and against. Benchmarking
competitions generally have a way of perverting code away from natural
style, regardless of the language; and this particular competition
outlaws the use of libraries (or at least it used to; I don't follow it
closely), which is a really big problem re comparing actual code in the
wild. Haskell is a very library-oriented language and uses lots of small
libraries, more like Perl's CPAN than like C libraries.
You can use Ptr Word8 to do unsafe things, but (Ptr a) is there to deal
with FFI stuff and interacting with C is always unsafe. People certainly
use it in real code when they need to marshall things back and forth
across the FFI.
