Yeh, ok, "not no main" is not a great example.

And actually I think if such a think existed the 'not' should be on the 
'version' instead of the identifier,
more like #ifndef VAR than #if !VAR

  !version(LeanAndMean) {
     // do some fatty stuff here
  }

The bottom line is, just because D doesn't have negative version checks, 
doesn't mean the need for them will go away.  It just means that
   "version(X){}else"
becomes the spelling of "!version".  I'd personally rather see 
!version(X) or not_version(X) than version(X){}else.

But either way it's not a big deal.  Just an odd thing to get all 
principled over.
