Hey folks!

I was prompted down this mode of thinking after answering some questions 
related to why `:ets` was returning argument error. Turns out they hadn't 
included the `[:named_table]` option. However the error message gave them 
exactly zero help when it comes to figuring out what is wrong.

`:crypto` is another good example where any number of things can go wrong, 
and all will result in the same generic argument error.

There's really two questions here:

1) Is it worth wrapping something like :ets or :crypto with an elixir 
module that could improve error messages?

2) Does this particular implementation idea I have sound reasonable?

I split it up this way of course because while #2 may be a bad idea, I 
don't want rejection of #2 to imply rejection of #1.


## Implementation notion.

By way of example, let's tackle that :ets problem

Ets.new returns %Ets{opts: [:named_table], ets_id: 123987}

defmodule Ets do

end
