Bjarne Stroustrup: Is multiple dispatch a good thing? - Yes.

"Languages that support multiple dispatch at run time (like Dylan and
CLOS) do better and languages (such as C++) that support it at compile
time can sometimes help a bit."

iterator and tuple with forIterator

As an experiment to become more familiar with nice, I decided to try
to build a new forIterator method for maps that allows you to iterate
over a tuple of key values.  The forIterator looks like the following,
and works fine:

<K,V> Iterator<(K,V)> forIterator(Map<K,V> map){
	let entries = map.entrySet().iterator();
	return (() => {
		if(entries.hasNext()){
			let entry = entries.next();
			return (entry.getKey(),entry.getValue());
		}
		return stop();
	}).iterator();
}

However to use the forIterator, I had to place a temporary variable as
the item in the for statement, then pull the values out inside the
loop.
void main(String[] args){

	Map<String,String> mapdata = listToMap([
					("test1","Bla1"),
					("test2","Bla2")
					]);

	//This works
	for(entry :mapdata){
		(String key, String value) = entry;
		println("Map Iteration Test:" key "=" value);

Overriding == for strings

As a simple test, I am trying to override the == operator for string
comparison.  The problem that I am running into is that I see no way
to do a reference test once you override the method.  In some
languages I have seen an === operator that always does a strict
reference test.  Is there any way to do something similar in nice?

Dan

Nice's DbC vs Eiffel DbC

Hi!

Nice has the special syntax for overriding methods in derived classes:

class Base { public void f() { …  } }
class Derived extends Base { f() { … } }

But, if a method defines precondition then there isn’t a possibility to  
override such method – compiler informs about syntax error:

class Base
	{
		public void test( String value )
			requires value.length > 8 : "value must be at least 8 symbols"
			{
				println( "Base#test: value: " value );
			}
	}

class Derived extends Base
	{
		test( value )
			requires value.length > 0 : "value cannot be empty"
			{
				println( "Derived#test: value: " value );
			}
	}

void main( String[] args )
	{
