• mascip commented on Improved autobox-ing. I'm loving it :o)

  My purpose here is both to share information and to learn. I said "hey, that's possible! Isn't that cool?", and then i listened.

  Some people said that they didn't like this syntax but they didn't explain why. I tried to guess and found some possible reasons; it made sense so i shared my thoughts.

  Although i like using "better new" syntax, I might not want to produce code on CPAN that others will struggle to read. I would like to use some amount of "newer" syntax, while making it simple to spot and integrate for others (or for myself in one year).

  A possibly good sol…

  I hadn't criticized the syntax, but I do have an example of something I'm not fond of and a reason why. I find the use of chained method calls without parens to be jarring.

  (0..9)->grep { $_ > 5 } ->map { $_ * 2 } ->join(' - ')

  This is, of course, all a matter of personal taste and I could get used to it, but it's not the way that Perl or most languages work. I can think of an exception: LiveScript; although I'm sure there are more.

  $ 'h1' .on 'click'
    alert 'boom!'

  Which compiles to JavaScript:

  You said that “(^10) is not as self-explanatory”.

  It’s not without understanding the fundamentals of Perl 6, like the operators, which are needed in order to program in the language or understand the code. Just like Perl 5 or Ruby has their own prerequisite fundamentals.

  $a  ..  $b  # $a (inclusive) through $b (inclusive)
  $a  ..^ $b  # $a (inclusive) through $b (exclusive)
  $a ^..  $b  # $a (exclusive) through $b (inclusive)
  $a ^..^ $b  # $a (exclusive) through $b (exclusive)
         ^$b  # 0  (inclusive) through $b (exclusive)

  Thanks for your comments Nick :-)

  Indeed, these bare blocks after a method call are disconcerting. I didn't even notice that. I guess that's why I compensated by putting them on distinct line: it's the only way i could make it look ok. I'm almost happy enough with the result.

  I think it's not only a subjective matter. The fact that it's not seen anywhere else means that our eyes are not used to it, they don't immediately know how to interpret it. The fact that there is a given programming culture is not subjective. It is an objective fact that we have to take into account. Al…

  Hey Nick. Ruby has methods who take a block as an argument. An example here with the Tree class (search for "Tree" in the page):
  

  The result is :

  a_tree.visit_all { |node| do_something_with(node) }

  which will perform an operation on all nodes of the tree. I like it.
  I still don't love how it looks. But i prefer writing the list name first, and then the maps and greps in the order in which they are execut…
