Hardware drivers are specialized tasks.  One thing that drives me crazy is 
the assumption that a language needs to be able to do everything, and if 
it can't, it can't do anything.

Note that languages encourage or discourage certain styles of programming. 
For example, C++, and to a lesser extent Java and C#, rather strongly 
discourages an applicative style of programming- primarily due to the 
costs of allocation.  You can do it, but it's going to be a fairly serious 
perfomance hit.  Ocaml, on the other hand, discourages an imperitive style 
of programming.  There's no performance hit, but there are some type 
issues and library support.

The point is that instead of bitching about how hard it is to implement 
the other language's solution in this language, to instead be thinking 
about the correct solution to implement in this language.
