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.
