How much overhead is it if you accidentally delete working code? Or if you change previously-working code and then you don't discover it for days and now you can't go back and figure out what your change was that broke it, and for that matter, you don't even know what your last working code looked like?

xoxo,
Andy

    [Corion]: Hmmm. I feel a Meditation coming on. I wrote a module, DBIx::PivotQuery, which returns a table-like set of rows (AoA) but some columns are generated from column values, like in an (Excel) pivot table or a ROLLUP command
    [Corion]: My current approach for subtotals involves rerunning the given query, with the hint to the user that they should use a temporary table if they want better performance.
    [Corion]: But I could create that temporary table in the module and use it for the improved perfomance directly instead.
    [Corion]: And the question is, what would be better/preferred ;-)
