I don't want to get to deep into a discussion of this, the last time I got into a discussion on GC in non technical, I lost days of my life. However: - Suggesting that I move to prism to get a gc makes as much sense as suggesting that you move to c++ to get a 64 bit compiler - As Phil said "It's horse for courses". In the areas you work in, gc is obviously of no use. In the areas I mostly work in, it would make my life much easier. - Personally I get tired of the "GC = laziness" argument. It's dismissive without any real thought. - I do know how to use reference counted interfaces and smart pointers. I use them for some things. However reference counting doesn't work for circular references without a lot of additional work. Adding to the opf I use would take more time than it would save.

The distrust of GC as a technology amongst experienced practitioners (as it typically is) of the black arts of software development stems from: - less efficient use of memory (*) - unpredictably distributed performance across application usage (*) - loss of determinism (debugging complexity) (*) GC assumes a vast over supply of RAM and an availability of application idle cycles in which to recover wastefully over-allocated RAM. The beauty of the GC framework (ref counted lifetime managed via interfaces) that Delphi ALREADY OFFERS (!) is that: - as you say with 'D', it's optional :) - it remains deterministic So don't you already have what you want? All you have to do now is use it. :) -- "Smile", they said. "it could be worse!" So I did. And it was. -----Original Message----- From: delphi-boun...@delphi.org.nz [mailto:delphi-boun...@delphi.org.nz] On Behalf Of Sean Cross Sent: Wednesday, 17 June 2009 14:02 To: NZ Borland Developers Group - Delphi List Subject: Re: [DUG] Embarcadero article I do use C# where it makes sense. It just doesn't make sense for the sort of shareware and desktop apps I mostly do. I have never understood the fanatical hatred of garbage collection that some Delphi developers have (not aimed at anyone in particular but if you either try discussing gc in non-technical, you will get a large amount of vitriol heading your way). It makes some things much easier, and some things harder. Optional GC such as in D seems reasonable to me, but apparently not to everyone.

I want Delphi as a C++ replacement with as few compromises as possible, not C#. That said, the C# programming model has things I wouldnt mind in the language - data bound objects, decent object inspector and the dynamic interface thingies. Of course, if you are doing 64 bit, would MPI support be too much to ask as well? -- Phil Scadden, Senior Scientist GNS Science Ltd 764 Cumberland St, Private Bag 1930, Dunedin, New Zealand Ph +64 3 4799663, fax +64 3 477 5232 Notice: This email and any attachments are confidential.
