  In my experience this usually means that there has been an unintended
type conversion, e.g. an intended hash has been collapsed to a list in
a parameter reference somewhere, or a list to a series of parameters.

Bingo.  This passes the (list) contents of the thingy $allshows points
to as individual parameters to param(), rather than passing the
reference to the list.  You want to specify the parameter as simply
$allshows.
