Lexical variables are intended for temporary use in a limited scope. Using them properly alleviates the burden of finding multiple names for variables with an identical purpose in different scopes. Declaring a variable with the same name in the same scope is valid semantically (it discards the previous variable and provides a new one) but is usually a mistake, and compiling the program with warnings enabled will generate the message "my" variable $var masks earlier declaration in same scope You should always enable lexical warnings as well as strictures.
