    type: decorator makes function `load` untyped

    Problems

    when using @inject, the decorator makes the function untyped despite the function itself is type-safe

  • fix: typing-extensions ver for Semantic Versioning

    fix: typing-extensions ver for Semantic Versioning

    Due to the Semantic Versioning decision of typing_textensions https://github.com/python/typing/tree/master/typing_extensions#overview

    Starting with version 4.0.0, typing_extensions uses Semantic Versioning. The major version is incremented for all backwards-incompatible changes, including dropping support for older Python versions. Therefore, it's safe to depend on typing_extensions like this: typing_extensions >=x.y, <(x+1), where x.y is the first version that includes all features you need.
