Re: $obj->method v.s. $obj->method()

[Bloodnok]

Your assertion, regarding the difference between $f; and &f();, doesn't ring quite true - consider

sub frobnicate {
  &foo;
  &bar();
}

The statement &foo; calls foo using a mirror image of @_ i.e. as passed to frobnicate - whereas, as you point out, &bar() calls bar with an empty argument list - but neither call i.e. to foo() or bar(), modifies @_ as passed to frobnicate.

The statement &foo; calls foo using a mirror image of @_ /.../ neither call /.../ modifies @_ as passed to frobnicate

By "mirror image" you mean the same, right? Just to be clear, the call &foo; may actually modify frobnicate's @_.

See Re^2: Using & in function calls (&foo != foo(@_)) for an example.
