晋太元中,武陵人捕鱼为业。缘溪行,忘路之远近。忽逢桃花林,夹岸数百步,中无杂树,芳草鲜美,落英缤纷。渔人甚异之,复前行,欲穷其林。 林尽水源,便得一山,山有小口,仿佛若有光。便舍船,从口入。初极狭,才通人。复行数十步,豁然开朗。土地平旷,屋舍俨然,有良田、美池、桑竹之属。阡陌交通,鸡犬相闻。其中往来种作,男女衣着,悉如外人。黄发垂髫,并怡然自乐。 见渔人,乃大惊,问所从来。具答之。便要还家,设酒杀鸡作食。村中闻有此人,咸来问讯。自云先世避秦时乱,率妻子邑人来此绝境,不复出焉,遂与外人间隔。问今是何世,乃不知有汉,无论魏晋。此人一一为具言所闻,皆叹惋。余人各复延至其家,皆出酒食。停数日,辞去。此中人语云:“不足为外人道也。”(间隔 一作:隔绝) 既出,得其船,便扶向路,处处志之。及郡下,诣太守,说如此。太守即遣人随其往,寻向所志,遂迷,不复得路。 南阳刘子骥,高尚士也,闻之,欣然规往。未果,寻病终。后遂无问津者。

- !ruby/struct:SM::Flow::P
body: A <tt>Range</tt> represents an interval---a set of values with a start and an end. Ranges may be constructed using the <em>s</em><tt>..</tt><em>e</em> and <em>s</em><tt>...</tt><em>e</em> literals, or with <tt>Range::new</tt>. Ranges constructed using <tt>..</tt> run from the start to the end inclusively. Those created using <tt>...</tt> exclude the end value. When used as an iterator, ranges return each value in the sequence.
- !ruby/struct:SM::Flow::VERB
body: " (-1..-5).to_a #=> []\n (-5..-1).to_a #=> [-5, -4, -3, -2, -1]\n ('a'..'e').to_a #=> ["a", "b", "c", "d", "e"]\n ('a'...'e').to_a #=> ["a", "b", "c", "d"]\n"
- !ruby/struct:SM::Flow::P
body: Ranges can be constructed using objects of any type, as long as the objects can be compared using their <tt><=></tt> operator and they support the <tt>succ</tt> method to return the next object in sequence.
- !ruby/struct:SM::Flow::VERB
body: " class Xs # represent a string of 'x's\n include Comparable\n attr :length\n def initialize(n)\n @length = n\n end\n def succ\n Xs.new(@length + 1)\n end\n def <=>(other)\n @length <=> other.length\n end\n def to_s\n sprintf "%2d #{inspect}", @length\n end\n def inspect\n 'x' * @length\n end\n end\n\n r = Xs.new(3)..Xs.new(6) #=> xxx..xxxxxx\n r.to_a #=> [xxx, xxxx, xxxxx, xxxxxx]\n r.member?(Xs.new(5)) #=> true\n"
- !ruby/struct:SM::Flow::P
body: In the previous code example, class <tt>Xs</tt> includes the <tt>Comparable</tt> module. This is because <tt>Enumerable#member?</tt> checks for equality using <tt>==</tt>. Including <tt>Comparable</tt> ensures that the <tt>==</tt> method is defined in terms of the <tt><=></tt> method implemented in <tt>Xs</tt>.
