Thanks for sharing your ideas.

I think consuming all of a range evaluating front and doing nothing 
should be the role of reduce with only one parameter (the range). That 
overload would take the range to be "exhausted" and return void. Thus 
your example becomes:

[1, 2, 3, 4].map!(n => n.writeln).reduce;
