"""View base class.
If C is a subclass of View, then C(x) creates a proxy object around
the object x. The actual class of the proxy is not C in general,
but a *subclass* of C determined by the rules below. To avoid confusion
we call view class the class of the proxy (a subclass of C, so of View)
and object class the class of x.
Attributes and methods not found in the proxy are automatically read on x.
Other operations like setting attributes are performed on the proxy, as
determined by its view class. The object x is available from the proxy
as its __obj__ attribute.
The view class selection is determined by the __view__ tuples and the
optional __viewkey__ method. By default, the selected view class is the
most specific subclass of C whose __view__ mentions the class of x.
If no such subclass is found, the search proceeds with the parent
object classes. For example, C(True) will first look for a subclass
of C with __view__ = (..., bool, ...) and only if it doesn't find any
look for one with __view__ = (..., int, ...), and then ..., object,...
If everything fails the class C itself is considered to be the default.
Alternatively, the view class selection can be driven by another aspect
of the object x, instead of the class of x, by overriding __viewkey__.
See last example at the end of this module.

Similar to caught exception objects in Python, explicitly clearing
local references to returned ``ExceptionInfo`` objects can
help the Python interpreter speed up its garbage collection.
Clearing those references breaks a reference cycle
(``ExceptionInfo`` --> caught exception --> frame stack raising
the exception --> current frame stack --> local variables -->
``ExceptionInfo``) which makes Python keep all objects referenced
from that cycle (including all local variables in the current
frame) alive until the next cyclic garbage collection run. See the
official Python ``try`` statement documentation for more detailed
information.
