D affects others

[Wanderer via Digitalmars-d]

It's very hard to keep up-to-date with all these successors to 
Java. Every half a year a new language appears, and it's always 
"better than all previous". :-(

D's const feature is nice and clear. But what made me "fall in 
love" with D, is 'immutable' modifier. No inner mutable pieces 
possible, no need to copy defensively (or copy at all), no risk 
of data corruption, no matter how complex your data is. Very 
clever idea.
