Hello monks, I have a perl program which calls user-defined library pm files with predefined functions. Each user-defined library also contains: 
sub AUTOLOAD { return undef; }

[download]
in case the user doesn't implement one of the functions, the library can still return an undef value for the unimplemented function. My question is this: how can my main program determine whether AUTOLOAD was called or an actual function exists that returned undef. Thanks a bunch, Michael
