[Mono-dev] C# source-to-source compiler

[Liang, Qichang (梁启昌）]

I am also looking for developing C#-based language extension, which
the compiler will compile to C# 4.0 code that calls *my* runtime
library.  The emitted C# 4.0 code will then go to the original dmcs
compiler, which will then produce CLI bytecode.

Are you suggesting that it is difficult for me to add keywords to the
C# system,

or it is difficult to make the dmcs compiler to emit C# 4.0 code
(rather than CLI code)?


Also are you suggesting that my language should base on extension of
the Boo language rather than C# language?

However C# is much more popular than Boo.............

Thanks!
