The Finally module is useful independently of the fiber management model provided by Picos_structured.
This also introduces a number of changes:
The 'resource finally type is renamed to 'resource template.
The 'resource moveable type is renamed to 'resource instance.
The semantics of let^ is changed such that it also releases the resource in case an exception has been raised in the scope.
A borrow mechanism is added, as the let& binding operator, to allow one to use a resource acquired as a 'resource instance before moving the resource to another scope.
A way to explicitly release the resource held by an instance movable is also added.
