user-visible env in GHCi sometimes wrong
Let M be the head module of a multi-module project.
First compile M and all below it to objects:
ghc --make M
Now start an interactive session with M:
ghc --interactive M
ghci loads object code for M and all dependencies.
Unfortunately the top-level env is then stuffed,
so that, for example
1 + 2
yields
<no file>:0: Variable not in scope: `+'
This doesn't happen if any of the modules have been
compiled to bytecode, which inclines me to believe
this is some difficulty with the renamer/typechecker.
This happens in the just-about-to-be-released 5.00.1
sources, and probably the HEAD too.
