You can't mix part of a function call in: "Mixed in text must 
form complete declarations, statements, or expressions." 
(https://dlang.org/articles/mixin.html)

In this case, it evaluates to a comma expression, which is 
deprecated. If you put the "writeln();" inside the mixin string 
it should form a complete statement and compile.
