stringraku 8 我试图按照平常的代码编写方式从用户输入中获得一个列表,但由于以下错误可能会出现意外失败: This type cannot unbox to a native integer: P6opaque, Str 代码行为: my @a = prompt("Enter list: ").words || (1,2,3); 如果我只输入一个数字,它就会失败。 什么情况下将 Str 转换为...
What are Perl 4, Perl 5, or Raku (Perl 6)? What is Raku (Perl 6)? How stable is Perl? How often are new versions of Perl released? Is Perl difficult to learn? How does Perl compare with other languages like Java, Python, REXX, Scheme, or Tcl? Can I do [task] in Perl?
在Perl 6(一种多dispatch语言)中,您可以找出是否有与名称匹配的方法。如果有的话,您将获得匹配该名称的方法对象的列表: classParentClass{ multi method foo (Str $s) { ... } } classChildClassisParentClass{ multi method foo (Int $n) { ... } multi method foo (Rat $r) { ... } } my $o...

Code written in Raku which was originally known as Perl 6 can be called from within a Perl program and vice-versa also holds true. Features of Python: It is easy to understand, learn, and master. Debugging Python code is easy as the code is simple. ...
Perl是我见过的动态语言中,依然坚持保留“引用”概念的。这里的引用不是指概念上含糊不清的“值类型 vs 引用类型”中的引用,更像是C的指针,或者是C++的引用。比如下面的Perl 5代码: my$a=1;my$b=\$a;# ref$$b=2;# de-ref and assignprint$a;# => 2 ...
我需要一份关于 * vs $_ vs $ 的指南。 这个问题问得多么好。那三种东西都是语法糖, 因为上下文转换, 它们能很好地避免折行和更少的 bugs。 我们从我们的老朋友主题变量 $_ 开始。在 Perl 5 中它刚好出现在每个 sub 的外面。在 Perl 6 中它出现在块的默认值之外。 my &block = { 'oi?' }; &bl...
