Here is an idea for a new scope in Java (could be
used in other languages as well):

void fill
( final int color
{ final int RED = 1;
final int GREEN = 2;
final int BLUE = 3; })
{ /* ... */ }

Now one can call this as, for example:

fill( GREEN );

But one does not need to write

fill( Class.GREEN );

or so anymore.

I'd quite like that. Ages ago, i had the idea of being able to write:

class Paintbucket {
public static final int GREEN = 1;
public void fill(int colour) {...}
}

Paintbucket p;
p.fill(.GREEN);
// ^ leading dot indicates use of receiver scope

Static imports have made both our ideas somewhat redundant, though.

I also want a SmallTalk-inspired 'call this method on the same object as
the last statement' construct, which i'd also do with a leading dot:

BufferedWriter invoiceWriter;
invoiceWriter.writer(total);
..newLine();
..write(tax);
..newLine();
