Reading C++ source code can obviously be a good way to learn and is just plain interesting when its a feature you know very little about. As far as standard library source goes this is difficult due to the uglifying of names.
Is the uglifying done through some sort of post-processing of the source code before it's inclusion in the standard library? If so, what happens to the original source code? Are there any repositories of non-uglified C++ Standard Library source code?
I'm interesting in looking at C++11 and soon C++14 features in particular.
I can't imagine maintaining code in this form would be very fun....
EDIT:
There's a proposal to do away with this process here.
