It's not that dependent types can't be implemented in OCaml, just that
they haven't. See, e.g., http://www.cs.bu.edu/~hwxi/DML/DML.html

I suspect the OCaml development team is not inclined to add "sexier"
types to the core language, though I can't say if there are any
specific technical hurdles preventing it (certainly, decidability is
an issue)...
