defmodule Recase.DotCase do

  Module to convert strings to `dot.case`.

  This module should not be used directly.

  ## Examples

      iex> Recase.to_dot "foo_barBaz-λambdaΛambda-привет-Мир"
      "foo.bar.baz.λambda.λambda.привет.мир"

  `DotCase` is the same as `KebabCase` and `SnakeCase`.
  But uses `.` as a separator.
