Re^2: How to call a sub-routine ref

[greengaroo]

Yes I know. Here is another example with an anonymous subroutine:

my $ref = sub {
  print "Hello World!\n";
};

# Both are equivalent
$ref->();
&{$ref}();
# But which one is best? That is the question!

Also, I don't do simple stuff like that, I have objects and callback functions and so on. Most of the time I have deep structures that returns functions, or objects, then I want to call that function or object method.

Let me sleep on it and I will try to provide a more concrete example.
