Re: Is there a way to find out what kind of ref an object is?

[santonegro]

the first thing that comes to mind is:

eval { keys %$ref } ;
print "its a hash" unless $@;

[ysth]

use overload '%{}'=>sub{{}};
sub new { bless [] }
$ref = new();
eval { keys %$ref } ;
print "is it a hash?" unless $@;

That'd be the correct answer most of the time - if an object promises says it "can do" a hash interface, its up to everyone but the most sneaky to go by that.
