# 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
```
