What i'm basically looking for is a way to 'undo' changes made to the symbol table.

If you make the changes within a scope, you can localize them such that they'll be automagically undone when the scope exits. 

sub foo { print "foo\n" }

{
    local *foo = sub { print "bar\n" };
    foo();
}

foo();
__END__
bar
foo
