I disagree. I have worked for decades with case-insensitive languages
and I have always treated $FOO and $foo as the same variable. It does
not matter to me whether it is written all upper case or all lower
case, it is exactly the same thing. I have worked with different teams
who had had entirely different standards - some like all upper case,
some like all lower case, all for different reasons. What I object to
is being told that I MUST use one case or the other just to be
*consistent* with everyone else, especially when I disagree with their
reason for choosing one case over the other in the first place. The
language has no difficulty in recognising a word regardless of its
case, and neither do I.
By introducing case-sensitivity you are suddenly saying that $FOO and
$foo are now different, which goes against the grain of everything that
I have been taught since my first day at school way back in the last
century.
The person who dreamed up case-sensitivity is a sadist and a moron who
should be publicly flogged. But that's just my opinion.
