Published 1.1.151
Enhancement: Added support for metaclasses that support the __getitem__
, __setitem__
and __delitem__
magic methods, allowing classes that derive from these metaclasses to be used in index expressions.
Bug Fix: Fixed bug that caused dataclass usage to break in Python 3.6 and older when using the polyfill library.
Enhancement: Added conditional type support for __setitem__
so a value with a type defined by a constrained TypeVar can be assigned to an index expression.
Bug Fix: Fixed bug that caused a crash in the tokenizer when encountering a string literal that is extremely long (>100K in length).
Bug Fix: Fixed bug caused by a variable assignment with a list expression on the RHS that was interpreted temporarily as a type alias declaration. Added more sanity checking on the type of the assigned expression for type aliases.
Bug Fix: Fixed type evaluation bug where Callable
is used to annotate an input parameter, and the Callable
return type is a union that contains a type variable.
Bug Fix: Fixed bug in constraint solver relating to replacement of return type of the form T when matching was performed against Type[T].
Enhancement: Added support for __builtins__
module symbol symbol.
Enhancement: Added support for type narrowing conditional expressions of the form a is False
, a is True
, a is not False
and a is not True
.
