Nice read... and it gives me a new feature idea for D! The article 
rants about default parameters not being very useful when you have more 
than one (something I agree with), then propose an improvement:

Would't that be nice to be able to use the 'default' keyword when you 
want to use the default value for a parameter? Should be pretty trivial 
to implement.
