(How) can I make a constant that is either zero or null

In the general case, I don't think this is possible in D
currently. (It will become possible if the proposed "multiple
alias this" ever gets implemented, though:
http://wiki.dlang.org/DIP66 )
However, various workarounds are possible depending on the
context.
Anyone have an idea on how to make this work?
Why do you need to?
Just use null for pointer types, and 0 for integers. D is not C;
you aren't *supposed* to be able to just copy-paste any random C
snippet into D and expect it to work without modification.
If that's not a satisfactory answer, please show some specific
examples of code that you don't know how to make work without
VK_NULL_HANDLE so that I can propose a workaround.
