Er ... no. Only if they have been exposed to case-sensitive languages or
systems.
In my view, case sensitivity was one of the biggest mistakes the Unixers
made in the first place.
However, it is now pretty common, though not universal.
Oddly, having argued this, I'm going to say something in favour of PHP5.
I'm not aware of all the ramifications (I haven't done a great deal of
PHP5 yet), but it always stuck in my craw having to say (in PHP 4):
class MyName ....
if (get_class($thing) == 'myname') ...
Now I've no objection to being *able* to do that, but being forced to
(because get_class($thing) will *never* equal 'MyName', which is what I
called the class) is wrong. So in this instance anyway, I prefer PHP5's
approach.
