> During query parsing, there are unnecessary types lookups happening. For example, in
the DSL query hive_table where name = \"bar-999\" select name, name is parsed into an identifier,
and it was doing a type lookup to see if a trait or class called 'name' exists. In cases like
this, the operands are fields, not types, and so a type lookup is not necessary and arguably
incorrect.
