---------------------------------------------+------------------------------
 When a function is declared const like
 {{{
 const int getState() const { return curState; }
 }}}

 The const at the return type is redundant. In fact it causes the compiler
 to generated a parse warning internally that causes extra code to execute.
 By stripping off the extra const the compiler does not produce a parse
 warning and the compiled object code is unchanged.

 {{{
 int getState() const { return curState; }
 }}}

 This defect has no effect on runtime. It is entirely for compiler
 correctness.
