> Currently the DOT extensions only supports Simple Identifiers:
> For example:
> * *{{tbl.foo(0).col.bar}}* is parsed as: *{{((`TBL`.`FOO`(0).`COL`).`BAR`)}}*
> However, this is not the case in regular Expression field, for example:
> * *{{tbl.col.bar}}* is parsed as: *{{`TBL`.`COL`.`BAR`}}*
> Parser should support both compound identifier, and simple identifier chain after a record type SqlNode.
> Similarly, parsing should also be consistent for other types of expression, for example
> * *{{tbl.arr[0].foo.bar}}* is currently parsed as: *{{((`TBL`.`ARR`[0].`FOO`).`BAR`)}}*
