I have had the understanding that the *intention* of primitive operations of tagged (record) types in some way can be looked at as an extension of the actual record - especially if one uses the dot notation. In this case I would expect (at least) a warning from the compiler.
I discovered the ambiguity when I accidentally did put in an extra component in a tagged record and with the same name as a primitive function of it (introduced long ago). Then the (old) primitive function suddenly seemed to give strange results :-) So after this experience I will be careful about possible name collisions between record components and primitive functions.
