Excellent point. You've flushed out a long-lurking bug -- thank you.

* Fix Trac #4127: build GlobalRdrEnv in GHCi correctly
GHCi was building its GlobalRdrEnv wrongly, so that the
gre_par field was bogus. That in turn fooled the renamer.
The fix is easy: use the right function! Namely, call
RnNames.gresFromAvail rather than availsToNameSet.
M ./compiler/main/GHC.hs -1 +1
M ./compiler/main/InteractiveEval.hs -18 +14
M ./compiler/rename/RnNames.lhs -1 +2
}}}
I added a regression test too.
