 It should do something like {{{:module + *ModuleWhereBreakpointWasHit}}}
 and remove the added top level symbols of
 {{{ModuleWhereBreakpointWasHit}}} when we leave it.
 The goal is so that the functions which are in scope when we hit a
 breakpoint are readily available for investigations of the values stored
 in the free variables of the selected expression.
 This feature request is a consequence of the dicsussion in this ticket
 http://hackage.haskell.org/trac/ghc/ticket/2740#comment:4

 ... and a realated thing: When I do something like {{{:module + ModName}}}
 and later I do {{{:module + *ModName}}} then the non-exported symbols from
 {{{ModName}}} are not added into the scope.
