Julian Hyde commented on CALCITE-1425:
--------------------------------------
I think any API is fine, as long as the javadoc is clear. Probably returning
{{Pair<List<RelDataTypeField>, List<String>>}} is best.
Or is it the case that the size of the returned list of fields + the size of
the returned list of names is always equal to the initial list of names? If so,
you don't need to return a list of remaining names: the caller can always
figure out how many were consumed, and how many are left.
