In what case is this true? If it is only to avoid some boiler 
plate then it is not a good excuse, IMO. You can usually avoid 
macros by restructuring composition (using multiple layers of 
templates).

Anyway, cpp is a separate language from c++ so it only affects 
AST related tooling that modify source files where macros are 
present. It is overall more separate than builtin textual 
substitution (which is generally a bad idea) since it is a 
discrete independent step that a tool easily can apply before 
analysis.
