Detailed Description

Type parameter in functions.

A type variable can be viewed as template parameter in c++ template function.

For example, in the following pesudo code, the TypeVar of f is TypeVar("n", kind=kShapeVar). This function can take in a Tensor with shape=(3, 3) and returns a Tensor with shape=(9,)

template<i32 n>
f(x : Tensor[i32, (n, n)]) -> Tensor[i32, (n * n)]
