Hi, Just been bitten by finding out that there are two ScalarSubquery expressions, one is a SubqueryExpression [1] and another is a ExecSubqueryExpression [2].
Could we have the ExecSubqueryExpression subclass called ScalarSubqueryExec to follow the naming convention in logical and physical plans? That'd help a lot (and I doubt I'm the only one confused). Thanks.
