Does D require the standard library to function? Or to be
more direct, does D as a language need its library, or core
library, to function correctly?
I have become very interested in how programming languages do
their magic; how they interact with the computer itself, and
their inner

Thx. Seems that I have to relearn a lot.

Correct. I do not know how to use `T' to determine the recursion depth of

There's very little writing about D's core.atomics(TDPL seems to
very barely cover them, I assume it's because it's aging compared
to the library.)
Is it safe to assume that they behave similarly to C++11's
atomics?

The operating system starts the program
Then the extern(C) int main() gets called.

I doubt that, because it's an open set (alias this, inheritance).
