> The SQL parser currently does not allow a user to pass an aliased expression as function parameter. This can be useful if we want to create a struct. For example {{select struct(a + 1 as c, b + 4 as d) from tbl_x}} would create a struct with columns {{c}} and {{d}}, instead {{col1}} and {{col2}}.
