Currently, the function `List.delete` only works for a single field. What I
want to add is the possibility to delete multiple fields by passing a list
of fields I want to remove.
Can be like this one:
```elixir
List.delete([:a, :b, :c, :d, :e], [:a, :b])
#=> [:c, :d, :e]
```

Hey Randson, have you seen `Enum.filter`? It does almost exactly what you want,
except for any enumerable, not just list.

Nice, thanks for the heads up. Yep, it works exactly the way I want. However, it would be nice to have that pattern matching option. Without having to call the Enum module. But yeah, if you guys think just using `Enum.filter` is enough. I’m okay. Thanks,Randson From: 'Andrey Yugai' via elixir-lang

You wouldn't be able to pattern match on the input being a list regardless
because you could have a list of lists and be wanting to delete one of those
lists.
For example:
```elixir
List.delete([[:a, :b], [:c, :d]], [:a, :b])
#=> [[:c, :d]]
```
And I generally agree with others that the Enum
The --/2 operator already does this. :)
iex(1)> [:a, :b, :c, :d, :e] -- [:a, :b]
[:c, :d, :e]

The `--` operator has an important difference in behavior from
Enum.filter/reject, though.
[:a, :a, :a] -- [:a]
[:a, :a]
