D - version ID enumeration

How about the following?

version(A, B, C) {  // <- Here!
    version = D;
}

instead of

version(A) {
    version = D;
}
version(B) {
    version = D;
}
version(C) {
    version = D;
}

Ditto debug.

If you request the power like #if of C, I think we need version ID
"expression".

For example, "windows.h" has this line:

#if !defined(_68K_) && !defined(_MPPC_) && !defined(_X86_) &&
!defined(_IA64_) && !defined(_AMD64_) && defined(_M_IX86)

version(!_68K_ && !_MPPC_ && !_X86_ && !_IA64_ && !_AMD64_ && _M_IX86) {

"&&" "||" "!", and, version numbers are necessary every ID.

#if defined(_WIN32_WINNT) && (WINVER < 0x0400) && (_WIN32_WINNT > 0x0400)

version WINVER = 0x0501;
version _WIN32_WINNT = 0x501;
version(_WIN32_WINNT && WINVER < 0x0400 && _WIN32_WINNT > 0x0400) {

But I feel it doesn't look good in complex pre-processor to D...

I've seen many constructs like the above, and they scream "rewrite the code" to me.

I suppose so.
But there are codes in "windows.h".
I've wanted to convert mechanically.

Thank you.
