Re^4: Unable to declare local variable with "use strict".

Strict makes you declare your variables.

Wrong.

Strict only prevents unqualified variables to default to package variables, by throwing an exception. Declaring a variable with my is only one of the ways to satisfy strict. But you may introduce a variable using local, our or use vars. Or use a fully qualified name.

no you can't, local doesn't declare!
