struct Wrapper {
  template <typename T>
  operator T();
};

int main() {
  Wrapper w;
  w./* invoke completion here */
}

When content assist is invoked at the indicated location, the completion proposal for the conversion operator looks like this:

  operator #0(void): T

and if selected, the inserted text is this:

  w.operator #0()

Unlike bug 515350, the desired behaviour here is less clear. Options I can think of are:

  1) Simple: just don't provide a completion for a templated conversion 
     operator.

  2) Fancier: when the completion proposal is selected, create a 
     placeholder box in the place of the type, where the user can enter 
     a concrete type.

  3) Even fancier: try to deduce the desired type from the surrounding
     context, falling back to (2) if a type can't be deduced.
