my (fooref) = shift;

I see many examples in the camel book where a
subroutine takes one argument and the one argument is
an array ref.

my (foo_ref) = shift;

There is however at least one example where it is

my foo_ref = shift;

I am trying to figure out if this matters. What would
shift care about list context? shift should still
yield one thing an array ref??? See page 356 in
the camel book, and page 224. (I think).
