Clear[Eternity,x];
Eternity[x_]:=Eternity[x];

Clear[EmptyQ];
EmptyQ[{}] := True;
EmptyQ[x_List] := False;
EmptyQ[x_] := Print["Argument to EmptyQ must be a list."];

 Here are 2 versions of the same anonymous function. The only
difference between them is that in the second version Function[g....
starts on a new line.

One of them works. The other generates a syntax error.
