You may be surprised to hear that the old C++ compilers actually did
this type of source code preprocessing so that existing C compilers
could be used. I assume this manipulation occurred at the abstract
syntax tree level, and was then pretty-printed (or more usually
"ugly-printed") back as C source code.
