Review comment:
Yes, this is something I wasn't absolutely sure. Generally speaking member
function should come after a record type. However, during parsing time there's
really no way to distinguish.
[CALCITE-2906](https://issues.apache.org/jira/browse/CALCITE-2906) is more
broader discussion on this (not just member function, but also affects DOT
operator after array element, expression, etc.
