Beyond 1.0

• trycast: Enhance to use TypeForm
  • Standardize TypeForm:
    • ▶︎ Draft/shepherd PEP for TypeForm so that it can move to typing module
    • ––
    • Wait for a Python 3.x to be released with TypeForm in typing
    • Revise imports of TypeForm to pull from typing module instead of typing_extensions when possible
    • Release 0.y.1 version of trycast
  • ▶︎ Implement TypeForm support in mypy -- https://github.com/python/mypy/issues/9773
  • Revise {trycast, isassignable} signatures to use TypeForm
• Fix outstanding major issues & enhancements in the v1.1 milestone:
  • checkcast: Add API to provide information as to why a type is not "assignable"
• Improve documentation:
  • Automate computation of code coverage % across all supported Python versions. Advertise in README prominently.
• Release 1.1.0 version of trycast.
• –––
• (?) Add support for additional common non-JSON types:
  • typing.Iterable
  • typing.Iterator
  • typing.Generator
  • typing.ContextManager
  • –––
  • ⎋ Consider special items supported by typeguard
  • ⎋ Consider special items supported by PEP 585 (Type Hinting Generics In Standard Collections)
