This works:
foreach(i; [0,1,2,3,4,5].parallel) i.writeln;

This works:
[0,1,2,3,4,5].each!writeln;

This won't compile:
[0,1,2,3,4,5].parallel.each!writeln;

Error: template tmp.each cannot deduce function from argument 
types !(writeln)(ParallelForeach!(int[])), candidates are:
/tmp/tmp.d(9):        tmp.each(alias fun, Range)(Range range) if 
(isInputRange!Range)
