I think the .NET VM will be more useful for languages like C#, Java,
Managed C++ and other static languages.  Perl, Python and Ruby are not
easy to run in .Net because they are to dynamic..

This is also one of the reason parrot is invented.  From the parrot faq.

11. Why your own virtual machine? Why not compile to JVM/.NET?

Those VMs are designed for statically typed languages. That's fine,
since Java, C#, and lots of other languages are statically typed. Perl
isn't. For a variety of reasons, it means that perl would run more
slowly there than on an interpreter geared towards dynamic languages.

12. So you won't run on the JVM/.NET?

Sure we will. They're just not our first target. We build our own
interpreter/VM, then when that's working we start in on the JVM and/or
.NET back ends.

In alot of sense parrot will be .Net for dynamic languages.
