I've occasionally lamented the fact that C# doesn't provide a full
macro-based preprocessor like C++ -- it would be handy in
situations like this to be able to use "#if __CSHARP__ >=
0x00020000" or something. (Other ones that I've particularly
wanted include __FILE__ and __DATE__.) There's also cases where
code repetition could be reduced significantly if macros could be
used.
On the other hand, it does make the language easier to read when
you know that something can't be aliased weirdly to something
unexpected. So the C#-ish approach to dealing with the repeated
code / multiple version issue tends to end up being the use of
some sort of code generator -- which is basically what ANTLR is
anyway :)
