| Subject: | AUTOLOADed methods fail 'can' test |
Important to me, perhaps trivial to others. If you run the attached script, you will probably see better than I can explain. I use &AUTOLOAD to catch calls to subroutine/methods that are defined, and in certain circumstances call other subroutines/methods. As in perltoot (I think).
Anyway, such is not caught by the 'can' test, and I presume it can't be unless it is passed a correctly instantiated object (which I guess is the subject of the test).
Anyway, hth.
perl -V is just the latest on Win32 and RedHat. If it turns out to be relevant I'll pass it on.
