Is this not a third reason? If so, perldiag should be fixed
I don't think so. The two fundamantal causes of the warning are that the variable doesn't yet exist, or that it exists but has gone out of scope. The OP's code is trying to access a variable that has gone out of scope - ie a file-scoped lexical that goes out of scope at the end of executing the require'd file
