Yes I get it and I've seen what happened to de facto standards before, i.e. IE html. That was a de facto standard too.
But I've seen many other good ideas been crippled due to one single proplem. They where not standardized.
So your actually making my point with phyton. Obj-c is not popular, it's only enforced by Apple to those who want to make apps for their products. Well you can if you have to use some c++ bridging but that is not the point.
Phyton is simply not popular, phyton is available on all major platforms. Obj-c is available to the mac users and linux user. How many linux users actually use GNU/Step? a few geeks. And most of them calling them selfs geeks don't understand the point of GNU/Step. If phyton got standardized like C. It may very well grow in popularity.
I'm not sure if C++ even is standardized at this point. But it may very well be as there has been some activity going around for achieving just that. Still a standard is better than free. IE was free too.
