The need for macros in C++ is greatly diminished by templates.  Unlike
macros, templates compile.  That gives them geniune safety.  Like
macros, they must be written correctly.  Unlike macros, they're checked
by the compiler.  

Replacing macros with templates was and is a goal of introducing
templates into the language.
