> Currently CAST is parsed in the main Calcite's Parser.jj. When parsing the
> target type parameter it only supports primitive types or MULTISET). It's
> impossible to cast to an inline fully specified Row type at the moment
> (Calcite 1.16).
> Probably CREATE TYPE in Calcite 1.17 is worth looking at, it should support
> CAST
