 Well, people do make mistakes and life is tough enough already, so why 
make it tougher when we can have a free sanity check?  I mean there's 
hardly any cost from the extra characters added and it can save someone 
hassle with debugging, which is always tough by definition.

 I've suffered from silly mistakes myself on many occasions, possibly from
being distracted in the middle of doing something, and while I figured 
things out eventually, it often cost me a day of effort or so wasted in 
chasing them.
