I'm a fan of parsing false version blocks, but it seems like there
should be some sort of exception for version blocks for a different

an unknown version of the language is in use? It's somewhat hackish,
but to me, that seems better than parsing it and giving an error
because of syntax changes.
How can it skip it without knowing the grammar?
#ifdef D_Version2
...
#else

#endif
D has a precedence of having preprocessor macros (e.g #line) even if it's
not a full-fledged preprocessor, and I don't see why it couldn't adapt the
same solution.
FWIW, C# has #if blocks, too.
