No functor support. Questionable if it would fit idiomatically with .net framework culture but not something you miss. In order of wish list to F#: - ability to create a structure isomorphic to GADTS - further enhancements to metaprogramming and how it does quasi quotation stuff - Support for Higher Kinds The above would ameliorate the need for functors too, I feel.
