The current Proto already allows to specify whether to hold by reference 
or value.

The new thing is that Proto 11 uses lvalue- or rvalue-ness to choose. 
This is irrelevant to NT2 however, since capture strategy does not 
depend on that.

Best thing to do is probably to make it lighter, keep separate things 
separate, and truly extendable.

For example, transforms seem too tighly coupled with the rest in the 
current Proto version, and their limitations are quite intrusive.
