Using operator macros in C#

[syjell]

In article Macros---extended-course.-Part-1 I saw the following:

"Operator macros allow one to introduce new operators into the language. ... Additionally, such operators would be accessible from C# (if the type in which they are defined is public)."

I'm already using Nemerle attribute macros in C#, which works great.

But I haven't managed to get an operator macro working in C#. Could someone provide a basic example?

Thanks!

You can compile C# using Nemerle compiler. It is one option.

That's exactly what I am doing. I compile C# using Nemerle compiler.
While doing this I can even use Nemerle attribute macros in C#. Additionally I also wanted to use Nemerle operator macros in C#. But the Nemerle compiler gives me an error: "Expected: statement".

Let's consider a very basic example, using the Nemerle swap operator "<->"

using Nemerle;
using System;
namespace ConsoleApplication1
{
  class SomeClass
  {
        static void Main()
        {
            int a = 1;
            int b = 5;
            a <-> b;
        }
    }
}

Compilation with ncc.exe results in:

SomeClass.cs(11,13): error : Expected: statement

What am I doing wrong? Could someone point me to the right direction?
Thanks!

Sorry you cannot do it.
Only macro attributes are supported.
C# is not designed as extendable language.
