VSC ，虽然还是预览版，但 Markdown 功能已经够用

@jiang42 Python 确实是强类型的 https://en.wikipedia.org/wiki/Python_(programming_language)
所谓强类型就是不同的类型操作之前需要进行强制转换，强制转换可以是显式的，也可以是隐式的

Swift 和 Python 不清楚，但是 Ruby 是强类型的，Ruby 的变量是“Duck Type”，隐式转换的前提是对象存在 to_s, to_i 这类转换方法。
eg:
a = 10086
puts a # 打印的不是 a 本身的对象，而是 a.to_s 返回的对象，隐式转换
a = "10086" # 为什么可以改变 a 的类型？Ruby 的变量是动态类型
puts a == 10086 # => false，为什么？因为 a 是 String，10086 是 Fixnum，强类型
puts 10087 == a.to_i + 1 # => true，显示转换类型，为什么支持调用 to_i ？Duck Type
puts 10087 == a + 1 # => no implicit conversion of Fixnum into String (TypeError)

如果想要看到
document.write('10086' == 10086); // => true
这类代码，我建议还是继续 JS 大法好吧

@lilydjwg C API 涉及到 Ruby 的实现问题了，这个确实，我有个项目每次升级 Ruby 解释器都要修改 Ruby 头文件，但这个和 Ruby 本身语法没关系。编码问题加个“#encoding:utf-8”基本解决，同样也和本身语法没关系。

我所知道的语法不兼容，唯一一例就是 1.9 之后“case ... when ...”结构里“when”的后面不能再加冒号了。不过加冒号和 “if ... then ...”、“for ... in ...”一样，都是属于照顾其他语言的用法，不是 Ruby 推荐的用法，不支持也好。

翻一下 Ruby 的更新列表，你会发现 Ruby 在早期语法确定以后，后续版本更新里鲜有重大变化，2.0 的关键字参数，也是在兼容原来语法的基础上增加的。Ruby 的每次更新重点几乎都是 VM、GC，今后还会有并发，并发其实还是和 VM 相关。
怎么说，家家有本难念的经吧，Ruby 自由的语法加上元编程的特性，让 Ruby 创造 DSL 的能力独领风骚，所以 Ruby 的开发团队不需要去纠结 Ruby 的语法，你改多了反倒浪费了 Rubist 的创造力，注意力可以全部放在如何让 Ruby 跑更快上面就可以了。

其他语言则是反过来，在实现了一个强大的 VM 之后，如何让语法更完善、开发效率更高就变成了他们的纠结的事情。最明显的例子莫过于 JS，拍黄片弱爆了，JS 才是世界上最好的语言（认真状）。

@lilydjwg 那是 Vim 的事，Ruby 升级除了 1.8 升 1.9 那次，其他时候都是升完直接跑的，但是说到底 1.8 到 1.9 语法也没有出现不兼容，只是因为 1.9 增加了字符编码，1.8 的代码需要加上 encoding 信息而已

@lilydjwg 求不黑 Ruby，我记得 Ruby 2.0 发布的时候，Matz 在演讲为什么要升级到 2.0 时提到一条， 2.0 完全兼容以前的代码，然后台上台下会心一笑
