c# - 当 C# 编译器是用 C# 编写的时，是否可以修改它？

Question

我想知道是否可以为了方便而实现一些新功能。

当它出来时，这可能吗？

Anders Hejlsberg 说:

It is one of the directions we are looking at for future versions of C#. Indeed, I see meta-programming as a piece of our bigger “Compiler as a Service” theme that we are working on for a future release. We want to open up our compiler so it becomes an API you can call to compile a piece of code and get back expression trees and/or IL. This enables a whole host of scenarios, such as application programmability, an interactive prompt, user-written refactorings, and domain specific languages that have little islands of C# imbedded in them.

他还在其他地方(在一次 Channel9 采访中)表示，他们正在将 C# 编译器的核心移植到托管代码，以实现这一点。

有一个demo这可从上一个 PDC 获得。 C# 编译器确实是托管代码。
