Define an
import sub, and use
caller
in the
import sub to find which package called
you. Given the package name, you can access the variable, once
you turn off strictness.
Note that your programming style is widely regarded as bad style.
Some maintainance programmer will come along, see the assignment
to the special variable in the calling package, without seeing the
variable used, and she will delete the assignment. The program will
then mysteriously break. This is using global variables in one of
the worst ways imaginable. You should consider either passing
the data to the used package when doing the use
statement, or by setting a variable in the used
package.
