Personally I prefer to have syntax for "blocks" like Ruby/smalltalk.
given the following example function:
int func(int a, delegate int(int) dg) { .. }

// call func with [something in this spirit is my favorite]:
func(someInt) { | int a, int b | return a+b; };

compare with the current D syntax:
func( someInt, (int a, int b) {return a+b;} );

compare with a lamda syntax:
func(someInt, { int a, int b => a+b } );

blocks are more useful - they are not limited to just one expression, 
and I think are a more general construct. lamdas/array comps, are just 
special cases.
