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
:)
