My thinking is that is functionB does...

return %myhash;

...then it's therefore returning a hash. In which case to pass a reference to that to functionA it would have to be...

$obj->functionA({ $obj->functionB() });

But if functionB did...

return @myarray;

Then I'd have to do...

$obj->functionA([ $obj->functionB() ]);

And it functionB did return...

return $scalar or return \$ref

Then it would be...

$obj->functionA($obj->functionB());

My problem is that I don't know which one of those four possibilities functionB is going to do, and therefore don't know whether to wrap it in braces (for a hash ref) or square brackets (for an array ref) or nothing (for a scalar, or if it's already a reference).

You have got me thinking however that I should always be doing the square bracket array reference however, because functionA can always find a way to deal with that.
