in reply to Writing CSV files

I'm pretty sure, having read the code, that you can subclass Text::xSV to do what you need. Or, rather, since tilly didn't write it to be subclassed, you might have to do some sort of redefinition of some of the functions, but it shouldn't be that painful. If you want some help, give us a working example of what you need and we can help figure it out.

Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
