A self-written C++ standard library

Design goals:

• NOT an implementation of the ISO C++ standard library, but instead an experiment to see what a stdlib that no backwards compatibility requirements might look like
• design-wise copy the Python standard library's APIs whenever possible
• minimize build times
• a single header includes everything
• KISS
• do not sacrifice too much performance
• Can use existing C libraries like pcre but not C++ libraries

API and ABI stability

Do both of these:

• Maintain perfect API and ABI compatibility
• Make it possible to change both in arbitrary ways

This seems impossible but is in fact fairly easily achievable:

• Put everything under pystd<year> namespace

• When release happens, copy all files from foo<year>.[ch]pp to foo<year+1>.[ch]pp and rename the namespace accordingly

• The old version remains forever frozen in time

• Arbitrary changes can be done to the new version

Anyone who needs to interoperate with code using the old versions can #include the old header and use things from its namespace as needed.

Limitations

Only tested with GCC on x86_64 Linux.
