Incorrect typing when using a default function

[Nabrok]

Given

.option('text', {
  type: 'string',
  default: function getTheDefault(): string {
    return 'default';
  }
)

Typescript gives the typing of the result string | (() => string).

However, after parsing without a value what I get for the option is the return value of the function, not the function itself.

As typescript now thinks text could be a function it won't work in places that expect a string.

The TypeScript types are maintained separately on DefinitelyTyped, so you might want to open an issue/discussion there too.
