[Serhiy Storchaka]

Serhiy Storchaka added the comment:

You can overwrite fieldnames getter.

    @property
    def fieldnames(self):
        if self._fieldnames is None:
            try:
                self._fieldnames = next(self.reader)
            except StopIteration:
                pass
        self.line_num = self.reader.line_num
        if not isinstance(self._fieldnames, ListInsensitive):
            self._fieldnames = ListInsensitive(name.strip().lower() for name in 
self._fieldnames)
        return self._fieldnames
