With the availability of casts (including OOP style casts), I don't think it's possible to overload simply from return type. Even in the current implementation, there are cases when the compiler can't decide which overloaded function to call. For instance, when the same parameter position of two functions are on the same inheritance line. Moreover, return values don't need to be assigned, it can be safely ignored. In that case, which overloaded function one has to call? Your case doesn't worth overloaded function, as the returned values has different meaning. -- View this message in context: http://free-pascal-general.1045716.n5.nabble.com/Overloading-functions-tp5720000p5720001.html Sent from the Free Pascal - General mailing list archive at Nabble.com. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
