I checked the interfacer and I am a bit sad to that it

1) Is "deprecated" and literally the first sentence states its use is discouraged because often such suggestions are misleading and bad advise.

2) From the readme it appears it just suggest to changes of parameter types in functions to existing interfaces. I was hoping to see something that suggests interface definitions from existing types based on whether share methods with same names.

About 2) I guess it is indeed kind of unnecessary as such suggestions are kind of trivial. On the ither hand I recently started to learn how to use interfaces and I have kind of a difficult time to wrap my head around how to make idiomatic use of that concept. So even such trivial help would actually be of some use to me, simply because it removes some cognitive load and I be able to see many examples (even potentially bad, but compiling ones) in front of my eyes.
