# Deal

This module is not about Monad or Maybe... it is just a shortcut

over the pattern `{:ok, value}`.

With **Deal**, you can write code like that:

```elixir

Deal.with! do

  f(1)

  g()

  h()

end

```

instead of:

```elixir

with

    {:ok, a} <- f(1),

    {:ok, b} <- g(a),

    {:ok, c} <- h(b),

do: {:ok, c}

```

You can checkout the [test file](test/deal_test.exs) for more examples.

## Installation

The package can be installed

by adding `deal` to your list of dependencies in `mix.exs`:

```elixir

def deps do

  [

    {:deal, "~> 1.0.0"}

  ]

end

```
