python-traits
The traits package developed by Enthought provides a special type
definition called a trait. Although they can be used as normal Python object
attributes, traits also have several additional characteristics:
* Initialization: A trait can be assigned a default value.
* Validation: A trait attribute's type can be explicitly declared.
* Delegation: The value of a trait attribute can be contained either
in another object.
* Notification: Setting the value of a trait attribute can trigger
notification of other parts of the program.
* Visualization: User interfaces that permit the interactive
modification of a trait's value can be automatically constructed
using the trait's definition.

- Update to 6.3.1:
* Make PrefixMap._map available again, for compatibility with Mayavi. (#1578)
* Support for Python 3.10 has been added.
* The observe mini-language now supports use of "*" for listening to all
traits on a HasTraits object. Currently this support is limited to
cases where the "*" appears in a terminal position. For example,
observe("foo:*") is supported, but observe("*:foo") is not. (#1496, #1525)
* The Any trait type now supports a factory argument (with accompanying
args and kw arguments). This can be used to specify a per-instance
default, for example with Any(factory=dict). (#1557, #1558)
* When a method is decorated with an observe decorator, the method
signature is now checked, and a warning issued if it doesn't match the
expected signature. (#1529)
* The Date, Datetime and Time trait types have a new argument allow_none.
(#1432)
* The Date trait type has a new argument allow_datetime .(#1429)
* The ObserverGraph instances that result from compiling ObserverExpression
objects and observe mini-language strings are now cached.
* The equality definition on ObserverExpression has been simplified. (#1517)
* A failure to parse an observe mini-language string now raises ValueError
rather than LarkError. (#1507)
* Invalid assignments to PrefixList and PrefixMap traits produced an
unnecessarily nested exception. This has been fixed. (#1564)
* An observe-decorated listener method whose name has the special form
"_traitname_changed" will no longer be triggered both as as result of the
observe decorator and the special naming: it will only be triggered via
the observe decorator. (#1560)
* The delegate parameter was mistyped in the typing stubs for the Delegate
trait type. This has been fixed. (#1556)
* The Function and Method trait types will no longer fail when arguments are
