/** CRTP here

*
|
|
* to be able to recover original type from a variant,
|
|
* we need some analog of dynamic_cast<>.
|
|
* We don't use c++ dynamic cast here because we
|
|
* are refusing to impose any restrictions on
|
|
* facet representation types, so in particular
|
|
* they will likely be of unrelated type.
|
|
*
|
|
* Instead rely on the interface pointer to access
|
|
* information about the runtime type associated
|
|
* with a stored fat-object-pointer representation.
