I have a problem with object types in therion: it seems that it is not possible to have a survey and a station which have the same name (see example included which perfectly compiles if one changes the cave1 and cave 2 to Cave1 and Cave2 for either the station names or the survey names). Is that a normal behavior? It seems to me that a correct typing should allow having the same names for surveys, stations and maps.
