Why does “return list.sort()” return None, not the list?
...om a coding style (popular in various other languages, I
believe especially Lisp revels in it) where a series of side effects
on a single object can be chained like this:
x.compress().chop(y).sort(z)
which would be the same as

The string (an in-memory object) abc would be serialized as 0x61 0x62 0x63 (ASCII) or 0x00 0x61 0x00 0x62 0x00 0x63 (UTF16) -- with or without things like NUL terminators or encoded l...

To only way in Java 6 or earlier is with a so called StreamGobbler (which you are started to create):

ret := make([]interface{}, s.Len())
for i:=0; i<s.Len(); i++ {

return ret

Your best option though is just to use the lines of code you gave in your question:
b := make([]interface{}, len(a))
for i := range a {...
