all this I'm saying is pre TDPL book stuff. After the book was out,
things stabilized. But way back, even more so before D2, it would happen
quite often. Again apologies for no references or examples, but this is
all stuff from 4-7 years ago so it's hard to remember exact cases.
I do remember though, that the turning point for this was when Andrei
joined the D team. Before that it was more or less like this:
Walter was the master compiler writer, wohoo, and if someone challenged
him to add a feature, it went in. In most cases maybe Walter wasn't
challenged directly, but someone in the C++ community would say "Ha,
wouldn't it be great if C++ had X!", and then if D didn't had X already,
it would get added, so Walter would go "Oh, you know what, D has X!!"
Little consideration was given to whether X was worthwhile or not in the
big picture.
After Andrei came on board, things improved and became more like:
Andrei: "Hold on, first let's see if the use case for X is actually a
real world need or not. If it is, let's see if it is not satisfactory to
use existing D language features to solve that use case. And if it's
not, only then we'll consider adding it. But even so let's try to add X
in a more generic way, so that it easier to implement and/or so that it
could solve other use cases as well."
