fair enough you think namespaces are not the right solution, what you think is the right solution then ?��

I told you. Namespaces are a solution, but they come with issues.

Then I misunderstood you but I am geniouly interested in what those problems are and I think the infromation is something others will find interesting as well.��

No. In the HPC world, a common held position is that Fortran code is 30% faster than C++.

Cannot even rememeber the last time a 3d graphics developers mentioned Fortran.I occasional frequent forums and mailing lists plus keeping in contact with Blender developers.��

I have heard that Fortran can outperform C++ in numeric computation around the percentage you mentioned but first time I heard that its generally faster.��

Language Benchmark seems to strongly disagree

of its widely criticized but then what benchmark is not

Remember that part of my job is to write compilers.

I knew that you write compilers (SmaCC) I did not realise you are a pro and especially on ones that generate highly optimised machine code

��

I'm also consider a guy to talk to when someone has deep issues with some of the new features of C++... even if I don't do C++, I can often reframe what the feature means in the overall scheme of programming languages.

On other hand I have close to zero experience on compilers��

I find it very interesting. I consider that current compilers are very good optimising code that is written in a language that obscures the developper intent in the first place.

I lost you there, you mean compilers for other languages than C++ ?��

As I told you, I work in a world where performance is paramount and C++ is strongly criticized for the fact its incidental complexity makes it very very hard to reach or maintain performance levels (compared to Fortran, say).

And I "work" in a world that C++ is the undisputed king , that's 3d graphics , though I must admit I try to stick with Python as much as I can.

In any case my point was that if namespaces can be done in a badly design language , should be possible in Pharo and easier. Not ease, just easier.��

Of course that's just a wild assumption but I hope this thread do not only disaprove my assumption but said a light in the real challanges of namespace implementation
