Hi I'm not certain how to approach this problem the best,
since libraries are compiled class files they are statically linked to the
clojure and c.c version they were compiled with. Please correct me if I'm
wrong. Now also between 1.1 and 1.2 some namespaces changed entirely so some

When extending a Java class in Clojure, what is a clean way to support
multiple constructors in the base class? Below is a sample of how I

two proxies. I used a

If you want to maintain backwards compatibility with 1.1, there are a few
gotchas:

My sense from the changes is that defrecord is the map-like one,
whereas deftype is the lower-level construct used to implement stuff
like clojure collections. I imagine users will use defrecord more
often than deftype.

That was my interpretation as well. I now have defrecord instead of deftype
everywhere. It looks like deftype was refactored into deftype and defrecord.
deftype implements none of the usual interfaces (IPersistentMap) whereas
defrecord does.

How about this:

As I understand it, map is, itself, lazy. Does that mean that using

What if often used functions such as map/reduce/filter were macros,

structures?
