为什么 Scala 库只定义了 Tuple22 以内的元组? [英] Why does the Scala library only defines tuples up to Tuple22?

问题描述

我很好奇是否有人知道为什么 Scala 库在 22 处停止，其元组类型为 Tuple22?
神秘数字22有什么特殊的隐藏含义吗?
这是某种内部笑话吗?

I'm curious if anyone knows why the Scala library stops at 22 with its tuple type Tuple22?
Does the mysterious number 22 have a special hidden meaning?
Is this an internal joke of some kind?

推荐答案

这个问题并不新鲜，参见 http://scala-programming-language.1934581.n4.nabble.com/Why-tuples-only-to-22-td1945314.html 或 为什么 FunctionN(0-22) ProductN(1-22) TupleN(1-22)?

This question is not new, see http://scala-programming-language.1934581.n4.nabble.com/Why-tuples-only-to-22-td1945314.html or why FunctionN(0-22) ProductN(1-22) TupleN(1-22)?

AFAIK 对此没有技术"解释，他们只是不得不停在某个地方.

AFAIK there is no "technical" explanation for it, they simply had to stop somewhere.
