F# = D + reflection

[bmeck]

The one big complaint for F#, OCAML etc is that they may have features but are not suited for programming system level code. For example, F#'s speed is comparable to C# which is faster than but comparable to Java. I use D for speed and a lot of meta programming using templates which I could use in other languages but it would be done at run time rather than compile time and require a large user installed library.
