David's use of quotes around object names raises another, moot,
question: if keywords and names were made case-insensitive, should
literal strings be made case-insensitive as well - for example, should
'max' == 'MAX' return True? I hope everyone agrees definitely not. I
challenge anyone arguing in favour of case-insensitivity for Python to
produce a succinct explanation for beginners of why names and keywords
are case-insensitive and why literals are not.

Of course, if literal string comparisons were case-insensitive, then
that implies that all string comparisons should be case-insensitive.
Follow that line of thinking a bit further and the fabric of the known
Universe starts to unravel...
