Well, you seem to be on my side but in anthoer corner
When we are talking about Gnustep outside objc view, developers has one main benefit: gnustep libraries that provide portable and rich libraries as a framework. as a programmer i like it but try to avoid objective-c and objective-c++ even more. gnustep ui are pretty cool to port wxWidgets or even tk into its backend. but why not to make this STEP more stright and provide some wrapper/binding to c++? So anyone can later do whatever he want using a c++ syntax without getting messed in objective-c++ every project.
Objc++ is something evil when it comes to syntax and code readabilty: two languages, many restricts to merge, and a strange convention . theorically you can anything possible using this latter, but its too ugly to people to handle it. That's why i would like to go further and make gnustep accesible outside using objective-c++ from the application-developers and other programmer
Hi Usama and all,
any thoughts on my suggestions?
BR,
Nikolaus

I know that i didn't invent something new or make things impossible as possible. I want to help people that like c++-syntax to consider gnustep as an option, after all.

So it may even almost exist but nobody did have the idea to make use of it. And it may be a much more manageable task than inventing a new wrapper and make people use it.
