was there a large breaking backwards compatibility break for C++? I was there for some of the Python2/3 transition but I’ve always thought C++ was adamantly backwards compatible (minor exceptions being stuff like auto_ptr/unique_ptr, which I don’t think was as big as a break as Python’s)

Sorry - I meant that C++ as an “improved” C never managed to remove C’s foothold, it just fractured the ecosystem,

When the c++11 abi break happened it was a big pain in the ass, but once MSVC decided in 2015 that they were going to stop breaking ABI I think it was the stability that c++ needed to fossilize…

Spoken as a C++ fan.
