Hi Hannes, I will improve docs and test, but for the moment I'll be away of my computer at least until Friday. Image persistance is not implemented.

Re: [Pharo-users] new chapter on double dispatch for new book :)

by Stephane Ducasse

a die handle is a group of dice as in 2D20. I'm not sure that I want to explain what is double dispatch up front. I want to go from the requirements to the solution How to add die (6) + die(5) die (6) + 2D20 2D20 + die(6) 2D20 + 2D10 Without doing a self class == Die Stef On Wed, Aug 23, 2017 at 1:38 PM, Dimitris Chloupis <kilon.alios(a)gmail.com> wrote: > I read it once without knowing what double dispatch is, after reading it , I > did not know what double dispatch is.
