My intention is to switch after an !TCL_OK return value from Tcl_EvalEx() to decide whether a TCL-related error has happend, or some POSIX system

Short of Tcl_ObjGetVar2("errorCode") and looking at the first element of
the returned list being "POSIX" in case of an error, is there a better way?
Tcl_GetReturnOptions()
