Eval in F#

let provider = new FSharpCodeProvider()

let eval<'outp> exp =

let main() = \n " + exp

let parms = System.CodeDom.Compiler.CompilerParameters(GenerateExecutable = false, GenerateInMemory = true)

let compilerResults = provider.CompileAssemblyFromSource(parms, [| source |])

let assembly = compilerResults.CompiledAssembly

let foo = assembly.GetType("foo")

let main = foo.GetMethod("main")

main.Invoke(obj(),[||]) :?> 'outp

Sorry about the indentation [:)]

.

If you use a service like github's gist, you it will do a better job of keeping the indentation etc.

Just curious--when you post an F# code snippet on gist--do you format as OCaml? I'd assume this is a yes. I wonder if we could get the gist folks to add F# as an option.
