Indeed; the extra referencing is being added by the \&buildlist($_), which is an unnecessary complication. There's no need to build a reference here at all, since buildlist() already explicitly returns one, and it's arguably confusing because \& is normally used to take a reference to a subroutine, not to a return value.

Removing the \& there would enable all the ${$$...}-type constructions to be simplified, so for example the assignment to @tmp would then become just @{$ref->[3]}. This is probably a Good Thing.
