improve N1QL query syntax error messages

N1QL query error messages are not very useful in identifying or fixing a problem in the query. Can we throw more useful syntax error messages. For ex: 

1) select * from[ default;

"code": 3000,
"msg": "syntax error - at ;",
"query_from_user": "select * from[ default;"

2) select *, from default;

"code": 3000,
"msg": "syntax error - at from",
"query_from_user": "select *, from default;"

3) select * from default where type = "order" let x = name;

"code": 3000,
"msg": "syntax error - at let",
"query_from_user": "select * from default where type = \"order\" let x = name;"

Thoughts to improve these errors:

==========================

1) print the line#,  col#, and the sample/surrounding text causing the syntax error. If line# &col# are not relevant, some way to identify the position# in the query text will be helpful.

2) Any contextual suggestion to identify/fix the issue would be great. In example (3) above, why let clause is error, or  suggesting to move let-clause before where-clause.
