Set, Util, and List are actually just interfaces, and Clojure's collections
implement them. The destructive operations throw
UnsupportedOperationException of course, which is actually explicitly
allowed by the spec:
* <p>The "destructive" methods contained in this interface, that is, the
* methods that modify the map on which they operate, are specified to throw
* <tt>UnsupportedOperationException</tt> if this map does not support the
* operation. If this is the case, these methods may, but are not required
* to, throw an <tt>UnsupportedOperationException</tt> if the invocation
would
* have no effect on the map. For example, invoking the {@link
#putAll(Map)}
* method on an unmodifiable map may, but is not required to, throw the
* exception if the map whose mappings are to be "superimposed" is empty.
This conversion is recursive; for instance, a List<List<Integer>> will be
internally stored as an immutable persistent List<List<Long>>. However,
this behavior is not documented, partially because it hasn't been tested to
my satisfaction yet and partially because validation does not currently
work with nested collections.
The library isn't available on Maven yet; I want more feedback on the
design before I make a commitment to the current interfaces, conventions,
and behaviors.
