Perl对Python 使用调查

reyleon

都学过一点儿，但是工作中不常用，所以也没多少长进

不服不行啊，这儿那儿总能看到.py

业余兴趣。由于我的工作信息量比较大，看过C语言基础，所以Perl比较适合我。
有段时间很耐心地想要学Python，因为Python脚本整体看起来很整洁，GUI方面的教程也比较多。
但也许是语法相差比较大，很久都没适应。现在又折返学perl了

    正在学perl，先把perl学会再学python

在perl 的论坛里，也只能找到用perl 多的吧

今天遇到一篇文章，说一个程序员如何从 Python 转到 Perl 6 语言的过程。

估计大家许多人看不到：

Before my involvement with Perl 6 I mostly used Python. However beautiful and flexible Python is, I worked on a project where it was a poor fit and writing proper test code was exceptionally uncomfortable. Thus, I often made mistakes – misused my data structures, passed values of incorrect types to methods – that I felt the language should be able to detect early without sacrificing flexibility. The "gradual typing" approach of Perl 6 sounded like a very good fit to me.

Having a friend show me bits and pieces of Perl 6 quickly led to looking at the Advent Calendar last year. I also joined the IRC channel and asked a whole bunch of questions. Not having done any Perl 5 programming before made figuring out the nooks and crannies of Perl 6 syntax a bit harder than I would have liked, especially when using the Perl 6 book. Fortunately, the IRC channel was always active and eager to help.

After having learnt a bit more about Perl 6, I quickly started helping out here and there. In part because I've already enjoyed doing that for PyPy – which is implemented in a subset of Python, much like Rakudo is implemented in NQP – but also because I kept hitting little problems and bugs.

主要原因是因为动态语言的通病：没有类型限定, 很多细小的问题很难被发现，项目一大，就抓瞎了。

Perl 6 的类型限定：

1. my Int $num = 1;
   
2. my Str $str = 'str';
   
3. 
   
4. sub check-args(Int $x, Str $y) { ... }

为了提高灵活性、降低学习成本把类型给淡化了，结果就导致大项目时有可能造成潜在bug。


   

化境

不知道为什么会有人认为用perl的都是单打独斗呢！我相信熟悉perl的人一定不会这么想。因为协作跟语言本身没有半毛钱关系；然大部分真正使用perl的并非是那些职业程序员，而是部分做系统管理工作的、部分dba、 做统计分析的、 在实验从事数据分析工作的、 黑客、unix/linux系统软件开发者等；我想这也是一些商业项目招perl程序员很难的原因吧。

只学过perl

如今我学习的就是perl，不管怎样。工具是用来工作的，不管什么工具，只要学好了自然有他用的地方。不足的地方在学其他工具补充就是！
