Your use of BEGIN is entirely appropriate for the code you posted. A normal sub definition is processed at compile time. What you're doing with the assignment to $get_strings is basically a sub definition, but since it takes the form of an assignment, Perl doesn't know that it should be handled at compile time. The BEGIN block forces the assignment to happen when it's needed. That's what BEGIN is for.

That said....

I don't see any real use being made of the neat features of a closure here. You could replace $get_strings with a normal subroutine &get_strings and it would work the same.

Perhaps you should choose a different sandbox to build this particular kind of castle....
