Does it matter?

At least one reason is for safety against misspelling. In
case-sensitive languages e.g. in C, if I had

   int an_Int;
   :
   <various other declarations
   
   for (An_Int = 1; An_Int < 10; An_Int++)
   :
   blah blah

and compile this I will get an error because of undefined An_Int. The
risk here is that I could just go to the declarations list and add:

   int An_Int;

rather than realising that I've just written an_Int incorrectly.

You can't.

This is another safety issue. If you want to comment out regions of
code use something like ada-mode with Emacs.


Hope this helps.
