I've lost count of the number of times I've hit an obscure 
failure because I added a new element to the end of an array or 
object without realizing the last element didn't have a comma. 
Most of the areas I'm responsible for already require this rule, 
and it's saved me a lot of headaches.

The use of COBOL cripples the mind; its teaching should therefore be
regarded as a criminal offense.
