in reply to Perl 6 shocking revelations #1
Compliments on your prose, and I don't often compliment people's writing. It's clear and succinct ... I wish there were more technical writers like you.
- Wow. This is my first introduction to Perl6 polymorphism, and, just, wow.
- The focus understandably is on the languages that most associate with OO programming, such as C++, Java, Smalltalk. However, your audience may be mostly Perl5 hackers. Consider including some additional verbiage (not too much, but a few sentences here and there) tailored to engineers who will naturally want to compare polymorphism to the object model of Perl5.
- At the top of page 4, s/the return the return types/the return types/.
- It's hard to believe the symbol for British currency is really being proposed for the language. Being an ethnocentric American, I wouldn't even know where to find it on my keyboard. A truly horrendous design decision.
Hope this helps!

Many thanks for the compliments. I am an accomplished writer, but programming magazines aren't what they used to be <sigh>.
I'm working on Perl 6 while I'm on sabbatical, and have been refactoring the documentation into a solid standard specification.
What more might I say about Perl 5 objects? I suppose I could be more explicit in summary, showing the typelessness and freedom compared with C++ etc.
The orthodox documentation has the "french quotes" like %h«hello $world». But every non-ASCII construct has an equivalent. I figured £ would be easier to type than ⍈. You're in China now, so maybe you can easily type 元? Seriously, I expect a lot of brainstorming over that. The important thing is to introduce syntax to correspond to the concepts — choosing a symbol not used for anything else let me not worry about messing up the existing grammar and be more succinct then discussing alternatives. It goes with the "shocking" part, I do think...

P.S. And add a table of contents.
But only if the references in the toc are clickable links.
Most of the pdfs I read that have tocs are dead text and give references in units, be they page numbers or chapter or section numbers, that bear no relationship to the actual pages as displayed in the bookmark section. Which makes them all but useless. Just so much extra junk that must be navigated to get to the real article.
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
