--------------------------------------------------------------
Implicitly converting strings to geometries would be great. SqlTypeTransform
sounds like the right approach; you will also need changes to
SqlTypeAssignmentRule (see CALCITE-3550). Add tests in
[TypeCoercionTest|https://github.com/apache/calcite/blob/main/core/src/test/java/org/apache/calcite/test/TypeCoercionTest.java].
Also update [the
doc|https://calcite.apache.org/docs/reference.html#implicit-type-conversion].
Can you log a separate case for this?
