$ perldoc Module::Name;
I don't know if the Module::Info gives you all of the
inherited methods; I certianly know that it cannot
extrapolate AUTOLOAD results a-priori (except for auto
split, and even that can be problematic).
Q: why would you want to use undocumented methods in
If you need to sanity check the calls before making
them then use "can":
my $obj = shift;
my $method = shift;
if( my $sub = $obj->can($method) )
# caller gets back the result of calling a
# method with passed in arguments...
$method->$sub( @_ )
# or an excption.
my $ref = ref $obj || 'unblessed';
die "Bogus object '$obj': $ref cannot $method";
