So If I get you right, because comments can lie, we should stop using 
comments ?
Computation never lies ? Well that's called a bug, and they are your 
every day worries.

Meaningfull names helps spotting miscomputation.

total_sales = some_computation()
How are you supposed to verify that some_computation is filling its role 
without even knowing what it is supposed to do ?

While I totally understand why some ppl prefer to use short names, I 
really don't see the point in saying that because any information can be 
wrong, we should stop giving any.
