http://play.golang.org/p/cUp0WhWv-c

package main

func main() {
    _ = complex(float64(1))
}
/tmp/sandbox460390042/main.go:4: invalid operation: complex expects two arguments, float64(1) returns 0 results

I would have expected it to say "1 result".

This appears to be fixed on tip. For:

package main
func main() {
    _ = complex(float64(1))
}

I see:

./x.go:3: invalid operation: complex expects two arguments

With gotype, I see:

$ gotype x.go
x.go:3:27: invalid operation: not enough arguments for complex(float64(1)) (expected 2, found 1)
