As we only have runtime checks for old style connects it would be nice to get errors already at compile time: 1) does the signal text match the method text 2) test whether signal and slot are members 3) test whether signal and slot are really signals and slots I think it's necessary to separate 2) and 3) to make 3) configurable to avoid false positives when compiling with icecream (preprocessed file). Thanks in advance! Cheers, André
