Itis defined there because Arrow is the name of the module and that symbol refers to the module initialisation function (or something like that, perhaps it's a module dependancy marker symbol). What seems to be happening is that the Arrow module in gtk2hs is clashing with the Arrow module in the lang package. As far as I can tell this all looks perfectly normal, so why don't we this kind of problem all the time? What's special about Arrow? How does it get resolved in the libHS*.a case? How does the system linker resolve the ambiguity when ghci's linker cannot?
