One can do better in C too:

1. Use pointers to structures wherever you can.
2. Write down data definitions:
   // a list is either null or cons(int,list)
3. Program as if you were in Scheme and pray that your c compiler 
understands GC.
4. Link in Boehm-Weiser.
5. Avoid pointer arithmetic until necessary.

There is a book on functional programming in C. If you ever need to 
program at that level, understand its lessons even if you don't follow 
them.
