- rewrite ppexpn.c to use a precedence parser
        - add new tests to check pp-expression parsing
        
- develop and implement CLIB optimizations
        - printf( "%s\n", p ); ==> puts( p );
        - printf( "%c", c ); ==> putchar( c );
        - printf( "sdasdsd" ); ==> fputs( "sdasdsd", stdout );
        - sprintf( buff, "%d", i ) ==> ltoa( buff, i, 10 );
        - strcpy( buff, "1234" ) ==> memcpy( buff, "1234", 5 );
                - or even better, ((long*)buff)[0] = '1234'; buff[4] = '\0';
        - type-checking on printf-style calls would be great

- i agree with first

- the second has marginal long-range benefit to a C++ compiler (but not a C
  compiler)
    - if we do do them, then we should implement them in a front-end
      independent manner, in a new codegen directory, so the C compiler can 
      also snag them
  
- instead I'd prefer to start to implement a debugging PLIB
    - implement the new/delete checking
    - implement the app call-trace now a macro in LEXUS
    - the intent would be to immediately support LEXUS; long-range to develop
      a debugging/statistics-gathering library
    - the run-time support could also be utilized by the C compiler
      
- we should aim to have a couple of small projects which will give her some
  familiarity with the C++ compiler and then to develop a year-long plan
  among the three of us
