And automatic memoization? Because common subexpressions can be
difficult to recognize but, at run-time, it is much easier to
recognize a function call that has already been done. Any common
compiler / interpreter which automatically memoizes? In theory, it is
also a huge advantage of "pure" functional programming languages.
