I'd find having that kind of syntax being too much magic, and I'd
actually like an indication that the module we import/create isn't
available as a python-file, but a .ui-file.

I'd be quite happy with syntax such as this:

<snippet>
from uiloader import ModuleFactory

mymodule = ModuleFactory('/path/to/ui/file/here.ui')
MyClass = mymodule.MyClass # if you really need the direct name

my_object = MyClass("some", "happy", "parameters")

# or if you really just need the class
mymodule = ModuleFactory('/path/to/ui/file/here.ui').MyClass

# or if you'd really like a class factory too, for convinience
from uiloader import ClassFactory
MyClass = ClassFactory('/path/to/ui/file/here.ui', 'MyClass')

</snippet>

Creating an implementation of ModuleFactory and ClassFactory should be
pretty straightforward as long as they use pyuic, which brings me to
my most important point: I _really_ want pyuic available as a module
in the pyqt-library, and not have to run it as a shell program.
