Continuation of #2548
Mini usability testing result out. Apparently the previous message was too confusing, so I'm adding back the fallback type clash msg.
Additionally, I'm now using
Ctype.matches
, which considersoption('a)
andoption(string)
as equal. This, along with the original code in #2548, fixes reasonml-community/error-message-improvement#14But since this produces false positives "missing parameters" msg for such code below:
Where
option(int)
matchesoption('a)
inferred fromSome("")
, I've also tweaked the msg to indicate that we're guessing that it might be because of missing parameters (but that we're not sure). The fallback type clash msg gives us leeway to guess.cc @cristianoc
