Comment (by mpickering):

 I reasoned that it didn't matter at all if `ghci` was being invoked
 programatically. In fact, it is more consistent to print out `()` rather
 than omit it.

 This was because it wasn't very convenient to insert this check in the
 `no-it` version as it worked before by checking if the type of `it` was
 `()`.

 Is it breaking your program?
