$data is a reference to an array (kind of like a c pointer):
$data = \@somearray; # or
$data = [1, 2, 4, 7]; # there are many other ways to create an array
ref
When you say @$data, you dereference $data into array context because
shift requires arrays to work with:
my ($type) = shift @$data;
Shifts the array that $data points to.

Subject: what is @$data
i have come a cross a array-scalar combo that i cant figure out, maybe
someone can help. the line off code is:
my ($type) = shift @$data;
does the $ in @$data mean to place $type after @data as opposed to
before in the new @data?
