I presume your intent is to have B inherit the implementation
from A. There are two options.
If you control class A and its appropriate to declare the
interface there, you can declare that A implements I and have B
simply inherit it from A.
class A : I {
int f(int x) { return x; }
}

Strictly speaking B does not implement function and inhereting

Yes, but it really seems like this is something that could and
should work..
If you control
To try and answer your original question more specifically. You
have told the compiler that B derives from A inheriting method f.
You have also said that B implements a virtual interface I. I
does not have an implementation, despite sharing a common
signature with f. If you just wanted f,
First, let me say thanks for the addition of the popcnt inline
assembler opcode. I had placed a project on hold until it was
available. I look forward to using D again.
I determined this instruction was available after some
experimentation as its not documented on the inline assembler
page.
Actually, I dropped the static if in my example and traded one
problem for another.
As the static variables of core.cpuid are not accessible at
compile time, I would like to emulate the cpu interrogation done
there, but I see that asm statements are disallowed in CTFE. Is
versioning the only
I retract my second concern. I misread a purity error for a CTFE
error. This does work as expected.
import core.cpuid: hasPopcnt;
/// Returns the number of bits which are set.
uint popcnt(ulong bits) nothrow
{
version(X86_64) {
if(hasPopcnt()) {

I would not make supporting an OS no longer supported by its vendor a priority,
particularly in light of the considerable efforts still needed elsewhere.
I see some recent additions were made to the inline assembler. Are there any
near term plans to support popcnt?

in D.
I agree. I do like the suggestion for developing the D grammar in Antlr though

Tiobe and others have tried to determine language popularity by various means.

That's funny. I read you original answer and laughed. It was too true!
I've been lurking on the forum for awhile, but thought I would join and say
hello. I've primarily been working with enterprise Java for the past 10 years,
but have a personal project better suited for a systems language. After a
cursory review of D, I am quite excited by what it offers and means
