Hi Jan, I’m sorry but I will not even look at it :( nothing personal, I respect a lot the instantiations people and their product (and I know they will do a good work). Is just that I care a lot about Pharo being open source MIT and I do not want to pollute my code with something I might have seen elsewhere (and copyrighted elsewhere)… But of course, I can discuss my idea here and with whoever wants :)
So, I have this idea who is very simple: keep structure offsets separately. Today all structure has something like this: height "This method was automatically generated" ^handle doubleAt: 17 height: anObject "This method was automatically generated" handle doubleAt: 17 put: anObject which of course does not work. with my idea this will become like this: height "This method was automatically generated" ^handle doubleAt: HEIGHT_OFFSET height: anObject "This method was automatically generated" handle doubleAt: HEIGHT_OFFSET put: anObject and HEIGHT_OFFSET can be initialised per session… or with a minimal intelligence per session with a “architecture changed” verification. I think this is very easy to implement and will work… but of course I still didn’t do anything more than think about… we’ll see when I try to implement it :) Esteban > On 5 Nov 2016, at 17:05, Jan van de Sandt <jvdsa...@gmail.com> wrote: > > Hi Esteban, > > Instantiations is also busy porting their VM to 64bits.
