Don't wait for C# 5, use Nemerle Now !!!

Hello ,
I mentioned nemerle before as C# glorified here . As you know C# 5.0 will came with compiler services that allows us to run dynamic code on runtime. Mono has already have it but it is not available to Windows at the moment (you can reference gmcs on windows but with limited support only). So here's our example:

using System;
using System.Console ;
using Nemerle.Evaluation.Evaluator ;

module Program
{
Main() : void
{
def function = EvaluateExpression( "x => x + 1.0" ) :> double -> double ;
Console.WriteLine(function(2.0));
}
}

The above code outputs 3!! Simply wonderful and best of all this code is in visual studio with full intellisense as below:

Just install nemerle from http://nemerle.org and add Nemerle.Macros and Nemerle.Evaluator as reference and run the code that's it!

Do you know that is a feature of Mono and not of NMerle? You can do this with C# on mono too.

@Paco : As you see in the screen shot this is windows only. Mono's that feature is not available on windows. This is certainly a nemerle feature

Umm, I think one problem with Nemerle is there's very little documentation available (tutorials and such) that one can peruse. Also, Visual Studio support is a bit thin on the ground - there's no IntelliSense for Nemerle, right?

Nemerle has a fairly large amount of documentation, but is it enough ? No unfortunately. There a lot more things to be covered but still you can ask to developers if you are stuck. They are quite responsive. For intellisense I added two more screenshots regarding your concerns
