Unforutnately, no.  As written the lambda is a runtime parameter, 
so there is no way the trait can get the actual function code.  
Instead, all that will print is the signature of the delegate.

If that were a template parameter, it would theoretically be 
possible to print the lambda expression, but as currently 
implemented it doesn't.
