This is so far true. I could not find a way of doing it in C#, yet.

>- no support of modules in MSC

This is not true. Vb modules are just classes restricted to have only static 
methods and tagged with the StandardModuleAttribute, so we have all modules 
OK in our C# implementation.

We need some help only with the first issue. The second one is already a no 
issue, but when the mcs compiler stabilizes to C# 2.0, we can adapt to use 
the new static class construct that already verifies that no instance 
methods are allowed.

Not yet.

Yes, but we nevertheless need approval from the Mono core team for such a 
beast.

I prefer to give a spin on my original idea, a multicompiler.

Mbas can accept many languages, besides VB.NET/MonoBASIC, It's a plugggable 
architecture. So we can embed mcs classes in it and compile in the same 
assembly code in C# and VB.NET, so it would be possible to keep the bigger 
part of MS.VB sources in C# and only the needed parts in VB.NET (we would 
need to implement "partial class" support from VB.NET 2.0 in mbas for that 
to work however)

Open for opinions...
