Fixes #19012. Fallback to return signatures without detailed types. These error message will be of the form of issue: * https://golang.org/issues/4215 * https://golang.org/issues/6750 So: func f(x int, y uint) { return x > y } f(10, "a" < 3) will give errors: too many errors to return too many arguments in call to f instead of: too many errors to return have (<T>) want () too many arguments in call to f have (number, <T>) want (number, number) Change-Id: I680abc7cdd8444400e234caddf3ff49c2d69f53d Reviewed-on: https://go-review.googlesource.com/36806 Reviewed-by: Robert Griesemer <gri@golang.org>
