Therefore I propose adding the general pattern. Simple example:
 >>> d = transformdict(str.lower)
 >>> d['Foo'] = 5
 >>> d['foo']
 5
 >>> d['FOO']
 5
 >>> list(d)
 ['Foo']
I guess another example is creating an "identity dict" (see http://code.activestate.com/lists/python-ideas/7161/) by doing
 d = transformdict(id)
