Yes, but that (as you mention) still leaves the question of how code that
looks like:

use strict;
$cust_data = {};

even compiles, since he should have gotten a

'Global symbol "$cust_data" requires explicit package name..'

compile-time error.

As noted, the the vars pragma is one way around the issue. If you're using
perl 5.6.0 or higher, you can also use the 'our' declaration, which creates a
lexically (not package) scoped global variable, which is very useful for
creating globals you don't want to keep around for the length of the program.
