1) Fix @ISA, or
2) Introduce real package scopes:
package Foo {
our @ISA = ...;
...
}
Not completely dissimilar to:
package Foo;
{
our @ISA = ...;
...
}
our() was never a problem for me, and if it is changed, some of my code
may break. I always prefer lexicals over global variables.
Consider code like:
our($MY_GLOBAL);
...
{
package SOME_OTHER_PACKAGE;
$MY_GLOBAL = $VAR_FROM_OTHER_PACKAGE;
...
};
Cheers,
mark
