Subject: loading IO modules causes methods to be inserted into other namespaces
Loading any of the core IO::* modules causes the global IO module to be loaded, which inserts all kinds of things into the namespaces of various IO submodules, even if they haven't been loaded yet. They aren't in a usable state by this point (among other things, @ISA isn't set), but this thoroughly confuses modules that want to check to see if a module has been loaded yet (for example, Class::MOP::is_class_loaded). It would be very helpful if doing "use IO::Handle" would only load symbols into the IO::Handle namespace.

All the IO modules share a common XS extension, so when that gets bootstrapped it will defined functions on the other namespaces. I would suggest that module attempting to determine if a module is loaded should be fixed.
