What are some common errors in Perl scoping?

Common errors in Perl scoping include using variables outside their intended scope, forgetting to declare variables, and misusing lexical vs. package variables.

Can you explain the difference between lexical and package variables?

Sure! Lexical variables are declared with 'my' and are scoped to the block they are defined in, while package variables are global and can be accessed from anywhere in the package.

What happens if I try to use a lexical variable outside its scope?

If you try to use a lexical variable outside its scope, Perl will throw an error indicating that the variable is not defined.

How can I avoid these scoping errors in my code?

To avoid scoping errors, always declare your variables with 'my' in the smallest scope possible and be mindful of where you access them.
