At last I've come to the end of whatever it is that I have written. I have tried not to let the "me" in the title intrude unduly on the text rather letting the computers and languages I have used and the people I have met speak for themselves. It's rather different than the paper I started to write. Possibly I should close as I have done in at least one earlier paper with a quotation from one of my favourite fictional characters:
"So there it is". said Pooh, when he had sung this to himself three times. "It's come different from what I thought it would, but it's come. Now I must sing it to Piglet."
