Hi,

I'm a beginning student in CS, and my classes are mostly in Java. I'm currently going through "Little Schemer" as a self study, and in the process of finding out how to do that I have found numerous references to "implementations" of Scheme. My question is, what are implementations?

Are they sub-dialects of Scheme, or is that something else (DrScheme seem to allow for different "flavors" of the language)? Is it just the name given to any given ecosystem incorporating an IDE, interpreter, interactive tool and the like?

Do all other languages (e.g., Java) also have a variety of "implementations", or is it something reserved to "open" languages?

Thank you,

Joss Delage

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
