How about returning a reference?
Just for test (sorry I have no perl6 installed on local device):
$ perl -le 'sub x {%hash=(1,2,3,4);\%hash}; print x->{1}'

I do not understand what you mean by "reference"?
Do you mean the key(s)?

&x

Be aware that they are not stored in the order you
place them. I have no clue why.
In Perl 5, we have a think called "reference".
It is a structure that points to another structure.
Basically, it a C Pointer on steroids. Perl 6 has
no such animal as it does not need one (YIPPEE!!).
