Description

Basically, this change would be a nice help with certain uses of map. If I wanted to get property "foo" out of a list of objects using map, I would have to do something like 

map(function(obj){ return obj.foo; }, listOfObjs);

Hardly a trouble, but it would be a little nicer to be able to write something like 

map(getProperty("foo"), listOfObjs);

instead. The function methodcaller does something similar, so it could be modified to attempt to return a property's value if it is not a function, but a function like getProperty would serve more uses.

You're lucky, if I understand correctly, this is exactly what Base.itemgetter does: http://mochikit.com/doc/html/MochiKit/Base.html#fn-itemgetter
