-------------------------------------+-------------------------------------
 Since b98ff3ccb14e36145404f075349c8689762a2913 was landed (#7253), you
 don't need `let` to define stuff in GHCi:
 {{{
 $ ghci
 Prelude> x = 3
 Prelude> x
 3
 }}}

 But when using `-fobject-code`, this results in an error:
 {{{
 $ ghci -fobject-code
 Prelude> x = 3
 Prelude> x

 <interactive>:2:1: error: Variable not in scope: x
 }}}

 Very strange.

 CC @roshats, who implemented this feature, but the bug is probably in some
 part of the code he didn't touch.
