魔塔游戏，在英文社区应该叫什么？就用粉丝们草拟的Magic Tower？

我带着这个问题，打开了[原始魔塔《Tower of the Sorcerer》的公认主页][英文网页])。

玩过英文版或访问过这个网站的盆友们都注意得到，作者的英文水平特别……小学生，强烈暗示游戏的英文是从某其它语言（粗糙）翻译来的。 而这个原语言极有可能是日文——网页左上角有个去日文版网页的链接，且俩版本都托管于同一个.jp顶级域的日文网站。 聪明好奇的我想到在日文网页上转转。如果猜想属实，作者的日文原文绝对比用英文写得清。

游戏的日文正名为《魔法の塔》。 嗯，正同中文取名《魔塔》，不知是洞若观火还是异曲同工。

According to https://bugs.ruby-lang.org/issues/17353#note-1, there were (if not still are) consistent posts requesting adding Elixir’s Pipeline Operator |> to Ruby.

However, unlike Lisp-1 languages like Python or JavaScript, Lisp-2s like Ruby face the additional challenge of namespace disambiguation. In addition to rightward calling, the Pipeline Operator would also change the call of the RHS to include the LHS. Therefore, its syntax is incompatible with the traditional designs for message passing programming and introduces a never-before-seen mental load.

# Proc and lambda share the same class {Proc}.
# {Proc#lambda?} queries if a Proc is a lambda or not.
# 
# You can create a proc with {Proc.new} or {Kernel#proc}.
# You can create a lambda with the `->(){}` syntax or {Kernel#lambda}.

# `&blk` converts block `blk` to proc (when receiving args)
# or procs or lambda to block (when passing args).

# Invoke a proc or lambda with {Proc#call}

REpresentational State Transfer

a fancy name for the CRUD support of a (web) server

• for the client-server model
  • implemented by typically web servers though HTTP(S), with data formatted in HTML, JSON or etc.
• treats server resources as OOP-style objects that can be CRUDed
  • a resource object can be a single item or a collection (as in OOP)
  • use client-side cache and server-side resources, not suspensive states (as with a “State Diagram”)
