Constructs
states
Although you aren't required to use the prefix unless two variables in
different scopes have the same name, for readability and processing speed,
it is recommended that you use prefixes. For example, the variable
"Form.lastname" is far more self-evident than a variable called "lastname."

Subject: Re: Documentation and numbers to back up best practices?
1. From Allaire dealing with memory variable overflows.
2. Best practice based on the order of evaluation of variables. Origin
unknown
3. Best practice from the SQL days that predate CF.
4. An article I wrote in Fusion Authority a while back (issue 8?). If you
look on www.houseoffusion.com in the Michael's Articles link you'll see it
in there.
