elixir 1.10.2 fixes

[ethangunderson]

When upgrading one of my apps to Elixir 1.10 I ran into a function clause error

        # 2
        :defp
    
        # 3
        :name_of_function
    
        # 4
        [{:http_result, [line: 347], nil}, {:\\, [line: 347], [{:ok_code_or_codes, [line: 347], nil}, 200]}]
    
        # 5
        []
    
        # 6
        []
    
    Attempted function clauses (showing 3 out of 3):
    
        def __on_definition__(_env, _access, _name, _args, _guards, nil)
        def __on_definition__(env, _access, name, _args, _guards, [do: _, rescue: _])
        def __on_definition__(%{module: module}, access, name, args, guards, [do: body])

The test suite already had a failure when running under 1.10, so I just added the missing function head. I also added the Elixir version under the travis config.

Let me know if there's anything else I should do before getting this merged. Thanks!

Nice, so was it a function head definition that was causing the error? ie:

def foo(bar \\ :default)

or was this some other case..

Yep, it was a function head definition.

Example of one from our codebase:

defp parse_response(http_result, ok_code_or_codes \\ 200)
