As I said:

By that, I meant to say that I just made that up.  I am sure that
various proposals have made some notational provision for `\ r -> r.field',
but it may or may not be `.field', I don't recall.

But that's all the magic there is to it.  Either you have a notational
shorthand for it, or you're obliged to write out `\ r -> r.field'
