The variable $# is deprecated, but this isn't the usage of $# here.
Here it is being used to get the number of elements in an array.
But the original code is buggy, and whilst 5.8 let that slip, 5.10
won't.
The original code the author was trying to write should have been
${$self->{__PB_TEMPLATE_LIST}}[$#{$self->{__PB__TEMPLATE_LIST}}]->param(
$param, $value );
Notice the lack of @{}.
But this is still far more complicated than it needs to be. It should
ideally look something like
$self->{__PB_TEMPLATE_LIST}->[-1]->param( $param, $value );
