All the `for' loops come to mind; the `for*' loops in particular are far 
more readable than nested maps and folds.

Functional hash tables, if HtDP doesn't already cover them.

Advanced macros: using syntax-case, syntax-parse, syntax parameters, 
lifts, and local expansion.

Typed Racket to statically enforce contracts, and for performance.
