First impressions of Roslyn CTP

I installed the CTP on my computer.
As you know the Microsoft Roslyn CTP enables the C# and Visual Basic compilers to be used as a service. Whereas today’s compilers are implemented in native C++, in Roslyn the compilers were rewritten from the ground up, implementing the C# compiler in C# and the Visual Basic compiler in Visual Basic. With these compiler rewrites, the Roslyn compilers become services exposed for general consumption, with all of that internal compiler-discovered knowledge made available for developers and their tools to harness. The stages of the compiler for parsing, for doing semantic analysis, for binding, and for IL emitting are all exposed to developers via rich managed APIs.
The Syntax Visualizer Tool is a Visual Studio Extension that enables inspection of 'live' Roslyn Syntax Trees for any C# code file that is open inside the Visual Studio IDE.

You can also see a graphical representation of the syntax tree. But you need Visual Studio 2010 Premium or Ultimate edition.

PegGrammar Macro article

I finished translation of the PegGrammar Macro article for Nemerle.
The PegGrammar - a macro-attribute of a class (applicable to classes) designed to automate the creation of parsers for various formal languages. It can be applicable to mainstream programming languages and to simple grammars such as those usually dealt with regular expressions.

Programming system MMIXAL.NET

RSDN MAGAZINE published my article Programming system MMIXAL.NET
Part1
Describes a programming system MMIXAL.NET. We consider the architecture of the virtual machine MMIX.
Part2
We consider loading and storing instructions, arithmetic and conditional instructions, bitwise and bytewise operations, immediate constants, jumps and branches, subroutine calls, system instructions.
