> tsc
node_modules/@mscharley/dot/dot.d.ts:419:74 - error TS2552: Cannot find name 'ClassDecoratorContext'. Did you mean 'ClassDecorator'?

419     <T extends object>(target: interfaces.Constructor<T, Args>, context: ClassDecoratorContext<interfaces.Constructor<T, Args>>): undefined;
                                                                             ~~~~~~~~~~~~~~~~~~~~~

node_modules/@mscharley/dot/dot.d.ts:433:34 - error TS2304: Cannot find name 'ClassFieldDecoratorContext'.

433     (target: undefined, context: ClassFieldDecoratorContext<unknown, T>): (originalValue: T | undefined) => T;
                                     ~~~~~~~~~~~~~~~~~~~~~~~~~~

The types used for ClassDecoratorContext and the other types related to TC39 decorators are only available in TypeScript 5.0 and later.

Steps to reproduce

Try to install in a project which is still using TypeScript 4.

Expected behaviour

DOT

1.4.2

TypeScript

{
  "type": "module",
  "exports": {
    ".": {
      "require":
        "types@<5.0": "./dot.v4.d.ts",
        "types": "./dot.d.ts",
        "default": "./dot.cjs"
      },
      "import": {
        "types@<5.0": "./dot.v4.d.ts",
        "types": "./dot.d.ts",
        "default": "./dot.js"
      }
    }
  }
}

dot.v4.d.ts can be generated by using grep to exclude every line containing DecoratorContext. This should be a fairly solid way to deal with it since we only need to exclude certain call signatures out of the decorator type definitions.
