I would prefer a patch for adding support for funcrefs in map/filter instead.
And it is also bad idea to only overload strings: if you need expressions here
use special value (like "expr") in place of {dict}, add second optional
argument or whatever, but **do not silently allow invalid function names taking
them as expression**. There already is a lot of places where vim shows strange
behavior with otherwise invalid input, don't add yet another one.
