Might as well just define ArrayBase etc

Sure, but what about all the places 0 is used to mean NULL?

Why not just keep it as printf?

No luck, dmd source uses #ifdefs mid-declaration, mid-statement, and 
mid-expression (even mid-string-literal)
It also uses #ifs with complex conditions.

And don't forget no-args ctors, implicit calling of ctors, stack allocated 
classes, new keywords, narrowing integer conversions, 'virtual', pure 
virtual function syntax, macros as expression aliases, string literal 
constness, the EXP_CANT_INTERPRET cast hack, macros, namespaces, macros, 
structs using inheritance, and of course more macros.
