@adonovan timeline kinda lines up with https://go.dev/cl/639157 and involves analysisinternal.IsTypeNamed. Maybe related?

My hunch is that within internal/analysisinternal/analysis.go in IsMethodNamed on the line _, T := typesinternal.ReceiverNamed(recv) that T is a nil *types.Named. ReceiverNamed looks like it can return nil on interfaces.

My hunch is that within internal/analysisinternal/analysis.go in IsMethodNamed on the line _, T := typesinternal.ReceiverNamed(recv) that T is a nil *types.Named. ReceiverNamed looks like it can return nil on interfaces.

Yeah. Classic Go bug. Thanks for investigating and fixing.
