A Collections Framework? Is there something Comparable ($\ddot\smile$) to the Java Collections Framework in LISP. I use functions like member, union, find, and stuff to design my algorithms but when they are to become productive with huge data sets I will need things like balanced-trees etc. and I don't want to re-invent the wheel. ... 24 May 2010 19:02
scheme problem This problem involves arithmetic expressions, which may or may not be numbered. You may need to use the following help functions in addition to the buit-in functions including eval which evaluates an arithmetic expression. For example, (eval (+ 1 2)) returns 3. Code: (define (atom? x) (not (list? x))) (define... 7 May 2010 21:09

I have most of the groundwork but cannot figure out how to actually insert the hook code into a function.
