What did you do?

I was very confused with what was wrong with my code:

Since gopls frequently errors out for whatever reason, I decided to check what go build says:

The object here is a zerolog.Logger (from zerolog), which provides Warn on a pointer receiver.

What did you expect to see?

Compiler error should be same as what go build gives.

What did you see instead?

Wrong compiler error.

Ah, thanks for reporting! This is another instance of a go/types error differing from a compiler error. I'll try to get a fix in for 1.15.

Change mentions this issue: go/types: improve errors for method calls with pointer receivers

The compiler has better error messages for methods called without a
pointer receiver when one is expected. This change is similar to
CL 229801, but for method calls.

Also, added better error messages for functions called with the wrong
capitalization. I left the third TODO in this switch statement almost
as-is because I'm not sure that the extra complexity is worth it -
I adjusted the error to look like the one the compiler reports.

Fixes golang#38658
