In search of a wormhole

[Michael Schuerig]

I have a generic widget for displaying sorted lists that is
parameterized with the name of the widget to be used for displaying and
editing individual list items. I now have a case where this item widget
needs additional information that is not passed through by the list
widget. Specifically, the item widget needs to access a data store for
auto-completion.

My current workaround is to use a global variable, but that's just bad.
I've thought of passing a "spiced" (curried with the store) item widget
constructor to the list widget, however, I don't see how to do this in
markup.
