D doesn't have anything like that. The compiler will generally move for 
you when possible. Passing an RValue to a function will be done as a 
move. When returning structs from a function, they're moved. For 
LValues, it's up to the caller to make the move with std.algorithm.move. 
There's been a good deal of discussion here in the NG about this. Hit 
google with 'dlang move semantics' and you'll get some hits. There's 
also Ali's presentation (video[1] and slides[2]) from last year's DConf.
