I found that no elegant way to express in D somthing like this:

#if(VerA>=4)
  // do somethig
#endif

#if(VerA>=3)
  // do somethig
#endif

#if(VerB>=2)
  // do somethig
#endif

I can write:

version(VerA_4)
{ version=VerA_3;  version=VerA_2;}
version(VerA_3)
{ version=VerA_2;}
version(VerB_4)
{ version=VerB_3;  version=VerB_2;}
version(VerB_3)
{ version=VerB_2;}
version(VerA_4)
{/*do somethig*/}
version(VerA_3)
{/*do somethig*/}
version(VerB_2)
{/*do somethig*/}

But what will be if I need VerA_10?

I think it is possible to introduce somthing like this:

version=VerA,4;
version(VerA,4)
{
  /*do somethig*/
}

The other way to reach the same result is to write static if in global  
scope.
Do somebody have any ideas about it?

In this case I must write something like this:

version(v5)
{
int k;
int j;
int i;
}
else version(v4)
{
int j;
int i;
}
else version(v3)
{
int i;
}
