Unconditional compilation?

Code in version blocks must be syntactically correct even if the
condition is not met and the code isn't compiled - ie, the compiler
still parses the code. But this makes writing libraries that compile
with both D1 and D2 difficult - I want to add features for D2 users
without having to distribute a separate version of the library.
version(D_Version2) {
struct SomeStruct {
// D2 copy ctor
this(this) {}
}
}
D1 chokes on that, which is expected behaviour according to the spec.
But how do I get the same behaviour as #if and #else - ie, tell the
compiler to completely ignore anything if some condition is not met?
