I repeat it regularly!

It's one of those things that one only learns the hard way, because the 
subtleties of it are not at all obvious. It's one of the mistakes that 
inexperienced language designers make again and again.

One of the other mistakes they make is the great idea of implicit declaration of 
variables, and then ruefully have to deprecate/remove it a year or two later. 
(How could those experienced designers have missed this obviously great feature?!?)
