I see no reason to diverge from that.
Welö, except for the fact that "any kind of variable" is not
well-defined for a language that supports user-defined alignment
restrictions:
---
struct Foo {
align(8192) byte b;
}
template Seq(T...) { alias Seq = T; }
void main() {
import core.memory, core.stdc.stdio, core.stdc.stdlib;
foreach (alloc; Seq!(malloc, GC.malloc)) {
auto mem = cast(Foo*)alloc(Foo.sizeof);
printf("%u\n", cast(uint)(cast(size_t)mem & (Foo.alignof
- 1)));
}
}
