Review comment:
> "All arguments of call to macro s.str should be literal"
From above exception message from JIRA description, I understands that only
literal is allowed for the macro.
If we support CAST, do we target to support some other expressions ? like
`select * from table("s"."str"(MAP['a', 1, 'baz', 2], 0 + 1)) as t(n)` ? Why we
take `CAST` into special consideration ?
