When not capturing the return value of a string mixin expression, I get "found `End of File` when expecting `;`"

This is the smallest example so far:
```d
import std;

void main() {
   (   mixin("(()=>1)()")  ); //it compiles and runs.
     mixin("(()=>1)()")   ;  //Error: onlineapp.d-mixin-5(5): 
Error: found `End of File` when expecting `;` following expression
}
```

What I learned today is that the second mixin wants a statement 
and does not accept an expression. It didn't liked the EOF which 
is appeared at the end of the mixin text.
