Summary

New bug fix release 0.12.1, which fixes a bug in the duck-typing type check logic and a bug causing the PropertyNotFoundTypeError error to be thrown as a stand-alone error although it is an error indicating the failure of a parent type check operation.

Detailed Changelog

Not present for website/docs changes

Changed

• Renamed:
  • Error MismatchingArgCountBetweenFuncTypesError to MismatchingArgCountBetweenFuncTypesTypeError.
  • Error UnknownTypeError to UnknownTypeTypeError.
  • Error PropertyNotFoundError to PropertyNotFoundTypeError.

Fixed

• PropertyNotFoundTypeError being thrown as a stand-alone error instead of being set as the cause for any parent
  assignment operation failure.
• PropertyNotFoundTypeError being checked for in the wrong direction i.e. that otherT had to have all the properties
  of thisT instead of the other way around (which is the correct way).
• Indexable checks for str and Array<T> being accidentally turned off by incorrect logic. This caused
  ValueTypeNotIndexableWithGivenAccessorTypeError to be only thrown for objects and not for arrays and strings.
