As pointed out by others one may choose a different string instead of "." like "->" if this makes the implementation of TDNR feasible.
Or, if both of these strings would make the implementation awkward, one can choose a different but similar, "~>", "-->" (to annoy bad syntax highlighters 8-)), which is neither special in Haskell syntax nor a prominent operator from a library. I wouldn't lay much stress on using the same notation as other languages. After all, we have (/=) instead of (!=) and it works.
But some mechanism to have some sort of scoped record selectors or TDNR is needed in my opinion.
I haven't needed the feature yet, but I think it would be A Good Thing™ to have it.
