Can't @ISA be used here?

From perlmod:

a package may also derive some of its methods from another class (package) by listing the other package name(s) in its global @ISA array (which must be a package global, not a lexical).
By using @ISA, no forwarding functions are needed if the methods are the same, so it's more efficient. It's also the standard practice. Is there some reason @ISA doesn't work in this situation?

Note: I'm no expert and don't know whether using @ISA invokes the AutoLoader, which you seek to avoid, but were I in your shoes I'd be doing inheritance in the standard way using @ISA and then dealing with any AutoLoader issues.

Update: I'm not clear on your constraint not to use 'bless', but the @ISA behavior works without bless. Note that the example in 'perlmod' is introduced as 'a traditional, non-OO module called Some::Module', yet it includes 

@ISA         = qw(Exporter);

(Updated again to ask about ISA working in this situation.)
