Summary: Call isa, can, does and DOES safely on things that may not be objects
 
How many times have you found yourself writing:

  if ($obj->isa('Something')) {

and then shortly afterwards cursing and changing it to:

  if (Scalar::Util::blessed($obj) and $obj->isa('Something')) {

Right. That's why this module exists.

Since perl allows us to provide a subroutine reference or a method name to
the -> operator when used as a method call, and a subroutine doesn't
require the invocant to actually be an object, we can create safe versions
of isa, can and friends by using a subroutine reference that only tries to
call the method if it's used on an object. So:

  my $isa_Foo = $maybe_an_object->$_call_if_object(isa => 'Foo');

is equivalent to

  my $isa_Foo = do {
    if (Scalar::Util::blessed($maybe_an_object)) {
      $maybe_an_object->isa('Foo');
    } else {
      undef;
    }
  };

Note that we don't handle trying class names, because many things are valid
class names that you might not want to treat as one (like say "Matt") - the
'is_module_name' function from Module::Runtime is a good way to check for
something you might be able to call methods on if you want to do that.

We are careful to make sure that scalar/list context is preserved for the
method that is eventually called.
