Technically, the -> is a binary infix dereference operator. In your case, since the right side of the operator is neither an array/hash subscript nor a subroutine argument list, it implies a method call with site being the method name and $tz could be an object reference or a class/package name.
The => operator is just a fancy comma. You can use it almost anywhere a , is used. Since this fat-arrow operator has the feature of autoquoting any Perl identifier to its immediate left (and also since it is eye-friendly), it is the preferred way to separate keys and values in a hash.

Detailed Description
template<typename _Tp>class std::slice_array< _Tp >
Reference to one-dimensional subset of an array.
A slice_array is a reference to the actual elements of an array specified by a slice. The way to get a slice_array is to call
operator[](slice) on a valarray. The returned slice_array then permits carrying operations out on the referenced subset of elements in the
original valarray. For example, operator+=(valarray) will add values to the subset of elements in the underlying valarray this slice_array
refers to.
Parameters:
Tp Element type.
