There's one caveat to this style. It'll break if this code is ever 
evaluated in a package other than main, so it should be avoided in a 
mod_perl or other Web server context.

It's fine in a defined package, but in that case it's probably better to 
go full OO and use $self, where $self is set to either the package name 
or an object blessed into that package/class.
