Is language support for collections is a coin feature ?

[Reinier Zwitserloot]

Sure, consistency is important. I didn't post these examples as a bid for
'this is to be the definitive syntax', just trying to show that within the
confines of the current syntax rules, there are plenty of options. What's
needed is a keyword or some other facility to quickly _produce_ the builders
that are required to make it all work. The annotations system can more or
less do this (the builders are new source files), though some
standardization or at least shipping it with java itself wouldn't go amiss.
These are much simpler options than changing the syntax itself.
