Function.From(functionType as type, function as function) as function
采用一元函数 function
并创建一个类型为 functionType

使用情况
Function.From(type function (a as number, b as number) as number, List.Sum)(2, 1)
输出
3
将接受列表的函数转换为双参数函数。
使用情况
Function.From(type function (a as text, b as text) as text, (list) => list{0} & list{1})("2", "1")
