Is there a linter for naked return of named return variable? A quick
google did not find one for me.

What situations would you like such a tool to report on?

Any case where a return parameter list includes named vars and the
return is naked:

func foo() (thing, to, pass int) {
// many calculations...
return
}

I cannot think of one but that thing is written in just a few lines. The question is why do you want to avoid that?

Thanks, Markus.

It's not a general thing I want to avoid, just in a package we are working on at the moment. Named return values are needed for documentation purposes and for clarity in the unfortunately huge functions (historical reasons) naked returns should be avoided.
