I get an error:
    
    
    Error: type mismatch: got <MyThreadType, proc (myThreadVars: MyThreadVars): 
Future[system.void]{.gcsafe.}, MyThreadVars>
    but expected one of:
    proc createThread[TArg](t: var Thread[TArg];
                            tp: proc (arg: TArg) {.thread, nimcall.}; param: 
TArg)
      first type mismatch at position: 2
      required type for tp: proc (arg: TArg){.nimcall, gcsafe.}
      but expression 'myThread' is of type: proc (myThreadVars: MyThreadVars): 
Future[system.void]{.gcsafe.}
    1 other mismatching symbols have been suppressed; compile with 
--showAllMismatches:on to see them
