Is there a way to identify the Windows version? Such as if it's
XP, Vista, 7, 8 or 10? Either some way to tweak with version
flags or something in the standard library.

Hello,
how can calling method on local struct throw "null this"?
struct is initialized by .init and have default values.
struct Foo {
Bar bar;
static struct Bar {
float x, y, z;
}
Bar getBar() {
return bar;
}
}
then
Foo foo = Foo.init;
auto b = foo.getBar(); // throw "null t
cast(ulong)&foo but is not null.
It won't work just in special cases what I cannot reproduce
easily.

Who could "someone" be? It's a self-contained example, and buf doesn't
leave the test function.

Why don't lambdas cast to a delegate if they are of type R

Can't find a function for it.
I would like to implement a "--version" switch for a command line
application.
Is there a clever way to do that without using the brain on every
build? :)
A dub-solution would be nice - but i didnt find it.
First, a reminder that we have this great resource of D idioms:
https://p0nce.github.io/d-idioms/#Rvalue-references:-Understanding-auto-ref-and-then-not-using-it
The link above has an idiom of mixing in a byRef() member function to a
struct. I think I've simplified the template by moving typeo
