How do these guards work in elixir_quote.erl?
Hi all,
I like to study Elixir’s source and I don’t know a lot of Erlang.
I got curious about these function declarations as I could not understand how a call to this function would match some guards.
We have in line 137:
dot(Meta, Left, Right, nil) when is_atom(Right) ->
then the next declaration in line 145:
dot(Meta, Left, {Right, _, Context}, nil) when is_atom(Right), is_atom(Context) ->
how does it work that the one in line 145 is ever reached? Same for the one in line 148.
Cheers!

{Right, _, Context} is not an atom but a tuple, therefore is_atom/1 returns false.
