I am a bit in the middle, I never cared or saw a practical benefit from static typing and neither I saw a practical benefit from using dynamic types. So its a matter that has little interest to me , but then I was never a language orientated person and I cared a lot more about IDEs and visual codin

[Pharo-users] Updating a project and NIL class variables

So my question is this , I have a class with nil variables that are lazy initialised only when needed the first time and of course they keep their values from there on. Lets say I get the latest update from github via metacello over an older update that I already have inside the image , do those v

Re: [Pharo-users] Updating a project and NIL class variables

They remain nil. That is why #initialize on the class side is needed. You can call that explicitly in a post load script, or rely on the class loading mechanism that normally calls #initialize automatically when loading a class. The warning is: this only happens when the *source* code of the #

[Pharo-users] Use cases for methods with optional parameters

Hi, I would like to study the impact of adding optional parameters to keyword methods in Pharo. The goal of optional parameters is to facilitate the implementation of methods where some parameters are optional. For example, Seaside has: WAComponent>>request: aRequestString label: aLabelString

Re: [Pharo-users] Use cases for methods with optional parameters

it would certainly save time from navigating through methods that more or less do the same thing. And of course dummy methods that they are there just to facilitate for less arguments. On Wed, Jan 20, 2016 at 7:42 PM Cyril Ferlicot D. wrote: > Le 20/01/2016 16:08, Damien Cassou a écrit : > > Hi,
