I should say so. When I were a lad we 'ad to scrape around for half a bit here and half a bit there - you didn't find whole bits just lying around in them days. As fer integers, you 'ad to save up for a year just to get sixteen bits. We used ter dream abaht 'avin' 64 bits, but there were no chance unless yer Dad were rich. Most of our strings were put together from characters we'd dredged out of t' canal, you 'ad to try and ignore the mud. We'd 'ave given our eye teeth for a bit of UTF-8 on a Sunday.
These kids wi' their Oracle databases didn't know they were born. I can remember 'avin' to optimise programs by making sure that the next instruction were comin' under the heads of t' drum just as the last instruction were finishing. But yer tell these young folk nowadays and they just don't believe yer. etc., etc. pythonistical-ly y'rs - steve -- Steve Holden +44 150 684 7255 +1 800 494 3119 Holden Web LLC/Ltd http://www.holdenweb.com Skype: holdenweb http://holdenweb.blogspot.com Recent Ramblings http://del.icio.us/steve.holden -- http://mail.python.org/mailman/listinfo/python-list
