I think you'll need to explain more about why you're trying to do that.

Tuples are typically related data of heterogeneous types, so it 
typically doesn't make sense (and nor is it possible without a common 
base class or type erasure) to return components individually in that 
sort of generic fashion.  Unless I'm just misinterpreting your example.
