minor: no period at the end of error messages (to match the go convention for fmt.Errorf).
gql/parser_test.go, line 3028 at r1 (raw file):
query { me(func: uid(0x1)) { friends @groupby(first: 10, SchooL: school) {
minor: I'd write this as friends @groupby(first: school) {. Otherwise it's unclear that first is an alias for a predicate. Right now it looks like first is another argument passed to groupby.

Maybe say "Can't use keyword %s as alias in groupby."
