Description

Previously Types.DeepMutable mapped over functions, resulting in

import { Types } from "effect";

declare const someFn: (arg: { date: Date }) => void;

declare const myArg: Types.DeepMutable<{ date: Date }>;

someFn(myArg);

/*
Argument of type '{ date: { toString: {}; toDateString: {}; toTimeString: {}; toLocaleString: {}; toLocaleDateString: {}; toLocaleTimeString: {}; valueOf: {}; getTime: {}; getFullYear: {}; getUTCFullYear: {}; getMonth: {}; ... 33 more ...; [Symbol.toPrimitive]: {}; }; }' is not assignable to parameter of type '{ date: Date; }'.
  The types of 'date.toString' are incompatible between these types.
    Type '{}' is not assignable to type '() => string'.
      Type '{}' provides no match for the signature '(): string'.(
 */

This fixes this while adding some tests for this.
