text/template: should eq permit comparison of signed and unsigned integers #7489
Description
Consider this example: // http://play.golang.org/p/wkyxTmGM0F import "os" import "text/template" func main() { template.Must(template.New("test").Parse(`{{printf "%T %T" (index . 0) 'a'}}`)).Execute(os.Stdout, "abc") } It prints uint8 int, which prevents using eq from comparing a byte to a rune constant, so one can't do {{eq (index . 0) 'a'}} Perhaps comparisons between signed and unsigned integer values should be OK if the sign is positive, or maybe even always.
