Curt,

Thanks for the feedback... this is very useful. Can you elaborate on 
what you mean regarding "same level of support for the DLR as C#"? Does 
that mean that VB won't be a dynamic language, but can use the DLR (eg, 
to host other languages)?

Also, it seems that a language that looked similar to C# or Java (or VB 
for that matter) could be implemented fairly straightforwardly using the 
DLR tools. Does anyone know of a project like that (that doesn't need to 
implement all of Java/C#/VB but just the main syntax/semantics)? Any big 
hang-ups in implementing such a (made-up) language?
