Hi and thanks for this great module,
I was wondering if you could add an option (unless it already exists and I missed it in the documentation).
I am currently dealing with CSV files that were transmitted from a remote computer somewhere in the nature to our server. There are often lines corrupted, meaning they can have more or less values than the header. I want to skip them (because they are corrupted) but not die the program (because next lines are good). I use the bind_columns but when there are more values I get the 3006 error and it gets out of the while. Putting an error_diag right after the while loop and checking for the 3006 error, I can then say goto beginning_of_loop, but this is not the solution I prefer... And I could not check if there was enough values to match the headers...
So what I imagine is an option in the constructor letting the programer choose if the number of columns matches the header (if any) goes on without reporting, make a warning that could go invisible or fetched in error_diag or make the usual error as now (unseen if no auto_diag but dies anyway). But I let you deal with the 'how'...
