My problem isn't with the built-in eval procedure but how to create a simplistic version of it. Just for starters I would like to be able to take this in '(+ 1 2) and have it evaluate the expression + where the quote usually takes off the evaluation.

I have been thinking about this and found a couple things that might be useful: Unquote: , (quasiquote) (apply)

My main problem is regaining the value of + as a procedure and not a symbol. Once I get that I think I should just be able to use it with the other contents of the list.

Any tips or guidance would be much appreciated.

Does R6RS or Chez Scheme v7.9.4 have a library function to check if a list contains duplicate elements? Alternatively, do either have any built in functionality for sets (which dis-allow duplicate elements)? So far, I've only been able to find an example here. The problem with that is that it doesn't… >>> More

In JavaScript is there a way to get the "value" of a statement in the same way that function() { return eval("if (true) { 1 }"); } returns "1"; function() { return if (true) { 1 } } and all similar permutations I've tried are not valid syntax.
