Unable to run _ByValue example

[Srikanth]

Hello Boaz,

This is a known issue - ATM, the VM does not yet handle the changes to 
signatures
that embed 'Q' in them to denote value types and it may be some time 
before the
VM support for this is fully there.

We are exploring some interim options to allow interested early access 
testers to
experiment with the usability aspects of the value type model (knowing 
that attendant
performance improvements are yet to come)

Stay tuned.
Thanks!
Srikanth
