# `Croma.Function`
[🔗](https://github.com/skirino/croma/blob/main/lib/croma/builtin_type.ex#L36)

Module that represents the Elixir's built-in function type.
Intended to be used with other parts of croma to express function variables.

# `t`

```elixir
@type t() :: function()
```

# `valid?`

```elixir
@spec valid?(term()) :: boolean()
```

Simply checks the argument's type using `is_function(var!(x))`.
