If Go adds generics, that's enough to enable many kinds of higher order functions without copying and pasting or ugly (and slow) reflection. A generic map, reduce, etc. are what I need. Across the thousands of developers in our organization I'll bet we've implemented "mapString" or "mapObjectThing" dozens of not hundreds of times. At least we could make a package for non built-ins. Also lots of interesting generic data types we need across our org that are a pain. With Java we have some data structure packages that Just Work and don't require copying and pasting.
