The Perl Conference in Amsterdam 2017 - Two Perl 6 classes and more

[Wendy]

Dear Perl Mongers,

We have added two days of training to The Perl Conference in 
Amsterdam.   The schedule is now complete with an extra fourth track 
and it is looking interesting and exciting ( 
http://act.perlconference.org/tpc-2017-amsterdam/schedule ) . Now you 
can have even more excitement by learning from the best: Damian 
Conway, Jeff Goff and brian d foy.  People who have proven they know 
how to teach you useful and high quality topics.  We offer each 
course for a nice price of just 150 euro per attendee.


It took us quite a while to get there, and I personally take the 
blame for the tardiness, and I apologize, and I realise that many of 
you already have booked flight or other means of travel, booked 
hotels and so on.  I hope many of you are still able and willing to 
join in.  The topics that brian, Jeff and Damian will lecture about 
are definitely worth your attention and effort.



brian d foy will improve your skills and knowlegde regarding Perl 5 
with his well-known and up-to-date class "Mastering Perl" on Monday, 
August 7.  On Tuesday August 8, he will go sideways, with attention 
to several small features of Perl in "Effective Perl 
Programming".  He is (co-)author of good-selling books with the same names.



Damian Conway will teach you how to parse Perl 6 code, using regular 
expressions and grammars, in his course "Parsing Perl 6" on Monday, 
August 7.  On Tuesday, August 8, he will impress us with his 
presentation skills and teach us how to be a bit like the 
presentation wizard that he is in the training "Presentation 
Aikido".  Many people have benefitted from this course when it comes 
to improving their presentation skills.  We offer this course as an 
extra service to the speakers of this conference for a price of 55 
euro, in the hope that it will help them make their presentations 
even better than they already are .



Jeff Goff will help you with your first steps in using Perl 6.  He 
has given this course several times before, at different conferences 
and workshops, while adding new content and adapting to new insights 
all of the time.  His training "Introducing Perl 6" is on Tuesday, 
August 8.  At the end of the day, you can make your first Perl 6 programs.



So, top content, top trainers, and on top of that, tea, coffee and 
lunch are included in each of the trainings.  Also, on Tuesday you 
can join early registration for The Perl Conference in Amsterdam, so 
you don't have to stand in line on Wednesday morning.



In case you did not yet register, please don't worry, we still love 
to have more attendees to the conference.  Register

Thank you for your attention.  I hope to meet you all in Amsterdam in August.

Kind regards,

Re: set (+) set = bag ?

[Parrot Raiser]

I'm tempted to ask how to classify "Yes, sir, no, sir, 3 bags full".
Does the constitute a Boolean, numeric, or set operation, or some
combination thereof? :-)*
