It is using System.Reflection.Emit, which means that there is
no intermediate IL source code generation involved.

The SymbolWriter is used to emit debugging infos. It's not a code

Jay, as a LALR(1) parser generator, is not limited to C# at all.

In the .NET ecosystem, compilers usually don't go down the
route of generating IL *source code*. Look at System.Reflection.Emit,
IKVM.Reflection.Emit, DLR depending on which kind of language
Scala is (I have no idea).
