@type scalar_list() :: [t() | [scalar_list()]]

An scalar list is a list that either contains scalars or scalar lists.

@type scalar_or_list() :: t() | scalar_list() | tuple()

Scalar or scalar list type specifier.

@type t() :: number() | :nan | :inf | :ninf | ExTorch.Complex.t()

A scalar consists of any value that can be stored in an ExTorch.Tensor struct.

It can be:

• Any number, floating or integer.
• The special floating point values :nan, :inf and :ninf, which represent the Not-A-Number, positive infinity and negative infinity, respectively.
• A complex value represented by the ExTorch.Complex struct.
