Is this equivalent to Foo!(a => a.writeln) or is it required to 
split this in two instructions as you did ? I also thought the 
parenthesis around the lambda arguments are not required. Is 
that right ?

Yes this is equivalent, the parens are not required. With a 
delegate literal they are: "auto foo = 
Foo!((a){a.writeln;})("hello");
