Failed to parse warning: [<: 1, >: 1]

[srevenant]

I figured out the "problem" — in a library module we have a function defined as a callback with a default function which has 'defoverride: ...' defined for this function.

Then in the module using this library, it overrides that function, but the function head had an optional argument defined:

def build(params \\ %{}) do

Taking out the \\ %{} resolved the error.

Environment

• Elixir & Erlang/OTP versions (elixir --version): Erlang/OTP 25 [erts-13.1.1] [source] [64-bit] [smp:12:12] [ds:12:12:10] [async-threads:1] [jit:ns] [dtrace]

Elixir 1.14.1 (compiled with Erlang/OTP 25)

• Which version of Dialyxir are you using? (cat mix.lock | grep dialyxir): 1.3.0

Current behavior

Please file a bug in https://github.com/jeremyjh/dialyxir/issues with this message.
