Along with all tests that assume AutoLoader::can works without a sub stub? Just to make sure: Do I understand you correctly in that you are saying AutoLoader should not try to work if there are no sub stubs in the user code (generated by AutoSplit or by hand)? I would assume that this breaks quite some code, no? Best regards, Steffen
Finally, this bug should be fixed by AutoLoader 5.65. can is now history.
