Perl: Question about 'BEGIN'

Newbie question, not sure of the use of BEGIN when you can just have the enclosed code inserted before the remaining program which means that code will get executed first anyway?

It's useful with -p and -n flags (usually used in one-liners).

A BEGIN code block is executed as soon as possible, that is, the moment it is completely defined, even before the rest of the containing file (or string) is parsed.
You need it sometimes.
