@jingham I'm confused, what are the requested changes? Because the behavior we seem to agree on is that we keep completions with the same value but different descriptions which is already the current implementation (see lines 138 and 148 in CompletionRequestTest.cpp)

Comment at: source/Utility/CompletionRequest.cpp:79
+  // Add the completion if we haven't seen the same value before.
+  if (m_added_values.insert(r.GetUniqueKey()).second)
+    m_results.push_back(r);

Also, when providing for example completions for the expression command, we would have the same function name with different argument lists. E.g.
  foo( -- int foo(int, int)
  foo( -- int foo(double, double)
