CSharp.Context.Execute(string) should return BoxedValue, not object

[axefrog]

The return value from a script could be any valid JavaScript value and these are most easily expressed and examined using the BoxedValue type. Rather than having to run through a big set of if/else statements checking the return type in order to determine how to treat the value, it would make more sense to return a BoxedValue object which has the appropriate properties and methods to do this efficiently.

We have to return object, in order to support dynamic interop.

The easiest thing to do is just use dynamic a = Execute(...); and do your thing with the a variable.
