I do not think it is that black and white :)

I agree that parameter names and global constants should have clear names,
(so code completion is actually useful) but for local variables, I do not 
think this is necessary.

Do you think this

   For MyVeryClearName := StartValue to EndValue do

Is better than this:

   For I:=S to E do

I hope not :-)

And it's not about the size of variable names. 
It's just about avoiding duplicate names which can lead to confusion.
