[N1QL UDF] n1ql syntax error is unclear

Originally had filed this bug because I thought it should upload successfully, but I now think theres no reason we would ever want to allow the uploading of a n1ql syntax error, however the exact cause of this uploads failure is not quite clear, I know that it is because of a problem with the n1ql statement, but it simply says unexpected token default, whereas the issue is actually before default

{throw "Syntax error at selec"} return acc;}'
Error while compiling library. Cause:
compilation failed:
Exception: SyntaxError: Unexpected token 'default'
Location: functions/n1ql.js:1
Code: function syntax_error() { try{ var query = SELEC * FROM default WHERE lower(job_title) = "engineer"; var acc = []; for (const row of query) { acc.push(row); }}catch(err){throw "Syntax error at selec"}

return acc;}
SyntaxError: Unexpected token 'default'

another error message that is hard to follow is this one (first mentioned in the comments of this bug)
ajaybhullar@SCML0613 ~ % curl -s -k -X POST http://172.23.104.110:8093/evaluator/v1/libraries/n1ql2 -u Administrator:password -H 'content-type: application/json' -d 'function call_func1( x ) { var acc = []; if (x > 5) { x = x - 1; var query = EXECUTE FUNCTION call_func1( x ); for (const row of query) { acc.push(row);}} else { return acc; }}'
Error while compiling library. Cause:
compilation failed:
Exception: SyntaxError: Unexpected identifier
Location: functions/n1ql2.js:1
Code: function call_func1( x ) { var acc = []; if (x > 5) { x = x - 1; var query = EXECUTE FUNCTION call_func1( x ); for (const row of query) { acc.push(row);}} else { return acc; }}
SyntaxError: Unexpected identifier

in this specific case, the reason it is failing is because x needs to be parameterized as $x instead of just x
