Dániel Dékány commented on FREEMARKER-131:
------------------------------------------
As of {{?map}}, the intended usage is just transforming a list of objects to a
list of some of it's property. That's needed for example if you have some
macros for common formatting tasks, which deal with list of strings for
example, but you have a list of user objects, each has a name. You can't pass
the list of user object to said macro, so you map it to the list of user names.
Also, we don't provide a way to efficiently build a list element by element, so
there wasn't even an acceptable workaround for such situations before {{?map}}.
