Comment (by mietek):

 As discussed on IRC with '''rwbarton''', it's questionable whether this is
 an issue besides "you're not supposed to do this".

 On one hand, GHCi claims it can load object files, and GHCi 7.6.3 does not
 crash when fed with an `.o` file produced by itself.

 On the other hand, feeding an `.o` file to GHCi 7.6.3 is not useful, as
 there is apparently no way to bring the functions declared in the
 corresponding `.hi` file into scope.

 I see two solutions — either adjust user expectations, or allow feeding
 GHCi explicitly with `.o`/`.hi` pairs, in the absence of an `.hs` file.
