TODO: deal with container namespace between widget parameters and user names

[tlambert03]

from magicgui.experimental import guiclass
@guiclass
class Person:
    name: str

Person('Alice').gui

File ~/dev/self/magicgui/src/magicgui/widgets/bases/_container_widget.py:336, in ContainerWidget.update(self, mapping, **kwargs)
    334     items = mapping.items() if isinstance(mapping, Mapping) else mapping
    335     for key, value in items:
--> 336         getattr(self, key).value = value
    337 for key, value in kwargs.items():
    338     getattr(self, key).value = value

AttributeError: 'str' object has no attribute 'value'

thats because Container.name conflicts with Person.name
