I think I'm just not explaining myself well.

Here's a rough example...

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

I want whatever function B returns to be passed as a reference to function A. I don't know what function B is going to return because that whole line is generated by a Parse::RecDescent grammar which is writing the Perl script based on the parsing of a scripting language I designed.

If I knew functionB was always going to return a list, I could do...

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

Or if I knew it was going to be a hash...

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

I've thought of writing a function which takes in some values and returns a reference to them, whatever they might be...

$result = $obj->functionA($obj->createrightreftype($obj->functionB()));

But I can't think of any way to make createrightreftype do the right thing.

Does that make any more sense? I'm finding it difficult to describe this.
