Marking this PR as WIP for now. I am thinking about the following two
approaches:
* Extend Origin(this PR): Extend and keep track of the user query text in
Expression.origin and show it in the runtime error message. Currently,
Expression.origin contains only the starting line number and position.
Example error message:
== SQL ==
select cast('a' as int)
--------^^^^^^^^^^^^^
* Use sql() + Origin: Show Expression.sql and Expression.orgin(starting line
number + position) in the runtime error message directly. Both APIs exist for
years and they are well maintained.
Example error message:
== SQL(line 1, pos 7) ==
cast('a' as int)
