"what parts of Lang would benefit from varargs"
Parts wherever you will have one or more parameter of the same type. Probably
places where you currently pass in a String[] or Object[]. The reason being
that previously, if you only had one parameter, you had to do
foo( new Object[] { bar } );
If the method signature uses var args you can now pass an array OR
foo( bar ); //or foo( bar, baz );
String.format( String s, Object... args ) is a classic example of its
usefulness.
Another thing to consider is with var args *I believe* you will _always_ get an
array instance passed in, whereas before you might have to do a null check:
foo( Object[] bar ) {
if( bar == null ) throw new IllegalArgumentException( ... );
}
foo( Object... bar ) {
for( Object o : bar ) // bar will never be null.
}
> Finally start using generics.

> It is obvious that the Jakarta project is reluctant in starting to use the
> 'new' (how old is it by now?) generics feature of Java. Nevertheless some
> other people would like to see it incorporated in the commons projects.
> I adapted commons Lang to usee generics. Took me about an afternoon. Would
> be nice if something is done with it, except for only me using it in my
> projects.
> Some stuff will have to be changed to conform to guidelines and stuff.
