確實是這樣（如果能不連想到資本市場的話）。 不過這裡上下文的脈絡主要是放在 conservation 「保育」上的，如 https://sfconservancy.org/

您好。真巧，我也是初二学历。 我很晚才学英语，但比较早学英文，主要是在 IRC 聊天室上聊自己感兴趣的主题 (当时是在 EFNet #mtg 上聊万智牌)，慢慢从对话里查字典学习一些词汇和惯用文法。 写长一点的文章时，可以参考 The Elements of Style，作为最基本的通用原则。

已修正, 感謝!

Dear Lin, The best way to choose among two languages is to learn both first. Learning Python makes learning Perl easier, and vice versa, so my advice would be start with learning from whatever your friend knows, and learn the other one so your friend can learn from you. :-) The Perl 5 Wiki has some information in books and online tutorials that you may find useful: http://www.socialtext.net/perl5/?perl_5_wiki#how_to_find_more_information Besides the excellent published books cited above, there is an upcoming book, "Modern Perl", that introduces a modern, concise and useful part of the Perl 5 language. Draft chapters are here: http://www.modernperlbooks.com/mt/2010/06/modern-perl-the-book-the-draft.html As for compilers, my first book on that topic was "Types and Programming Languages" by Benjamin C. Pierce; it's a nice book and I sincerely recommend it. Hope that helps! :-)

當然可以，我的網誌是 CC0/公領域，請逕轉。 Pm 也說過了，希望愈多人看到愈好。:-)

Jed, that's a great question. For Perl-specific, runtime-verified gradual typing, Moose::Manual::Types is a pretty good start. For a glance on compile-time verified gradual typing, please refer to Siek and Wadler's POPL 2010 paper and chase the references. :-) Also, Siek's PEPM 2010 keynote, General Purpose Languages Should be Metalanguages, is a pretty good read on (one of the many) motivations of Perl 6 development...
