Helpers to create paths from Access.t() and lists
Note:
This module is separate because functions presented in this module are suboptimal. You should try usePathex.path/2first, and only if its not applicable to you use-case, you should use functions from this module
Link to this section Summary
Functions
Creates path-closure from Access.t().
Creates path from list of items. The list of items should not be known
at runtime, therefore some optimizations of paths are not possible. Use this
function only when Pathex.path/2 is not applicable
Converts path-closure to Access.t()

@type access() :: [term(), ...]
Link to this section Functions
Creates path-closure from Access.t().
Note: Paths created using this function do not support force operations yet
example
Example
iex> import Pathex
iex> p = from_access [:x, :y]
iex> 10 = view!(%{x: [y: 10]}, p)@spec from_list([any()], Pathex.mod()) :: Pathex.t()

example
Example
iex> import Pathex
iex> p = from_list [:x, 1, :y]
iex> 10 = view!(%{x: [1, [y: 10]]}, p)@spec to_access(Pathex.t()) :: [Access.access_fun(any(), any())]
Converts path-closure to Access.t()
example
Example
iex> import Pathex
iex> access = to_access path(:x / 0, :map)
iex> 1 = get_in(%{x: %{0 => 1}}, access)
