Having skimmed the page, it seems like the re-use of "." is one of the
major difficulties of the proposal. Would it be possible to use "->"?
It has been used for accessing members in C and C++, so it is not too
unusual a choice. It is already special in Haskell so it wouldn't break
anyone's code -- but do its other uses (case statements and lambdas)
mean that it would cause problems in the grammar if re-used for TDNR?
