Parsing with Perl 6
The only thing I regret is that matching non greediness
has not been
made the default. Larry is discussing this
His concern is that greediness is disconcerting for
beginners but he laters goes on saying that non greediness
is too. Strangely his favorite argument "Huffman Coding"
is not invoked here. Personally, I add the "?" modifier
by default and supress it when it would break my regexep...
like in the exemple given by Larry
my ($num) = /(\d*)/; # greediness needed
So, because in my use, it is prevalent, I think that
non greediness should be made the default but I have not checked
other people code to see if they use non greediness more than
greediness. Also I don't know if changing the default
would affect the ratio of greediness/non greediness usage claimed to
be 10/1 for perl 5.8 in an answer to this nodelet.
Anyway, this ratio seems to show
that criteria of Huffman coding would lead
to a different grammar
decision choice for me than to most of people.
Also, I don't think that
new feature introduced in perl6 regexp would change this
