[ #4963 ]

So, I'm trying to overload the iterative operator: , which, according to the camel, is possible. However, I'm running into a slight problem:

my $data = <$obj>;

causes my iterator sub to be called once, in scalar context.

my @data = <$obj>;

causes my iterator sub to be called once, in scalar context.


wantarray returns false no matter how I pervert my calling method, and I can't figure out why.

    How are you overloading? I sometimes find overload doing different things whether I give it a string (the name of my function) or a reference to it.
    • Hmm, passing it a reference to a sub, rather than an anon. I'll try an anonymous sub, but I've not got much hope at this point :-)

      cheers for the tip though, will let you know how it works out.
