[KronicDeth]

By changing a module's name, you mean the alias after defmodule?

[JanStevens]

No the name of the module

defmodule Whatever -> defmodule WhateverYes

[KronicDeth]

@JanStevens I arbitrarily chose anything > 3 as a suspect size for the set size to protect from #767 in #771, but it turns out that > 3 can happen because defimpl can take a list for for and each of those generate a module. For example defimpl Poison.Encoder, for: [Range, Stream, MapSet, HashSet] has canonicalNameSet (Poison.Encoder.Range, Poison.Encoder.Stream, Poison.Encoder.MapSet, PoisonEncoder.HashSet). So, I'll increase the suspect size cutoff to 10, I guess. The error also points out that if the guards are zero-length, so is this read-ahead, so it doesn't give good output. I'll disconnect the read-ahead length from the guard length too.
