One of these delivered the customer requirement: an egg. The other is still working on an egg incubation framework.

I work with Qt and that framework has preferences for avoiding a lot of modern C++. I generally agree that it makes better code.

Also, I started with C++ in like 1992 and some part of me still feels like templates are newfangled nonsense.

Any “customers” landed are going to be friends and family, if not just outright fakes invented by leo.
