in reply to 0**0

0**0 in maths is not defined, but it would be nice if it was 1.
I think Perl contributes to this.

Google gives some interesting links:

    Every math teacher and such I've run across in the past 7 or 8 years at least has told me that 0^0 was eventually defined as equal to 1.

[ELISHEVA]: what's curiouser is that the underlying Text::CSV_XS appears to be BOM-friendly
[afoken]: DBD::CSV has a csv_class attribute. You could subclass Text::CSV_XS to handle BOMs, e.g. through File::BOM.
[ELISHEVA]: Text::CSV_XS already can handle boms - see its detect_bom flag
[ELISHEVA]: but it seems that the DBD::CSV layer on top of it doesn't
[afoken]: Also: All other attributes that start with csv_ and are not described above will be passed to Text::CSV_XS (without the csv_ prefix).
[Discipulus]: what about a good 'ol SOPW?
[erix]: Giro d'Italia won by Dumoulin (peccato Nibali)
[ELISHEVA]: csv_detect_bom doesn't work either
[erix]: (SCNR)
[ELISHEVA]: I may have to resort to SOPW - but was hoping that this would be something simple
