typescript - 使用带有 TypeScript 的 Ramda curry + 占位符导致“类型‘占位符’不可分配给类型‘x’

Question

我想用 Ramda 将已知参数绑定到回调，其余部分未指定：

import * as R from "ramda";

type Params = Partial<{
  param1: number;
  param2: number;
  param3: number;
}>;

function getBoundCallback(params: Params) {
  const { param1, param2, param3 } = params;

  const callback = (p1: number, p2: number, p3: number) => {
    // do something
  };

  return R.curry(callback)(
    param1 || R.__, 
    param2 || R.__, 
    param3 || R.__
  );
}

但我得到：

TS2769: No overload matches this call.
  The last overload gave the following error.
    Argument of type 'number | Placeholder' is not assignable to parameter of type 'number'.
      Type 'Placeholder' is not assignable to type 'number'

这样做的正确方法是什么？

我能想到的唯一解决方案是：

const callback = (
    _p1: number | R.Placeholder,
    _p2: number | R.Placeholder,
    _p3: number | R.Placeholder
  ) => {
    const p1 = _p1 as number;
    const p2 = _p2 as number;
    const p3 = _p3 as number;

    // do something
  };

这远非最佳。

这样做的正确方法是什么？

我"types/npm-ramda#dist"用于 Ramda 类型声明。
