I agree, this is bad use case and I'm glad that D didn't allow it.

Right and I believe that setting compile time constants in 
compiler command line would benefit everyone.

I think that `version(V >= 5)` is not harder to understand than 
`version(V.5)`. But `V >= 5` clearer defines that it's true when 
V==6 which is not obvious with `V.5` - you need to get used to 
that.
