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

in reply to $obj->method v.s. $obj->method()

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

sub frobnicate {
  &foo;
  &bar();
}
[download]

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.

A user level that continues to overstate my experience :-))

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. lodin	[reply] [d/l] [select]
