I came across when writing a macro that created functions after atoms.
I had the idead that to convert from atom to string, we could
interpolate the atom into the string, or we could use Atom.to_string/1.
Interactive Elixir (1.2.4) - press Ctrl+C to exit (type h() ENTER for
help) iex(1)> atom = :foo :foo iex(2)> atom |> Atom.to_string
"foo"
iex(3)> "#{atom}"
"foo"
iex(4)> atom = :nil
nil
iex(5)> atom |> Atom.to_string
"nil"
iex(6)> "#{atom}"
""
Is this a bug?
