I should have read on before posting because you made the same remark
that I did about your example.  Sorry about that.

But your original motivation was for an expression that worked in
unusual situations where such things have not been redefined.  There's
an expression that does what you want that does not use any identifiers,
but it fails (as Thomas pointed out) in strict code.  I don't think
there is a solution but I can't prove it.
