Episode 65: We Almost Always Get the Default Wrong - a podcast by Phil Nash & Jon Kalb

This week we chat with Vittorio Romeo about the pros and cons of backwards compatibility in C++, and his proposal to get the best of both worlds: Epochs.

As well as language compatibility, we also discuss ABI compatibility - why breaking these things is such a problem, but how not breaking them is increasingly becoming a problem.

We also, finally, get an answer to the age of question of, "how many programmers does it take to change a lightbulb?"

Special Guest: Vittorio Romeo.
