Discarding data is a very subtle business ;-) I'd be content with
translating (, ,) as (\, \,) and (. .) as (\. \.).

I.e. commas and periods are token constituent characters. Easily arranged in
the readtable.

Any tricky cases? Could the data contain instances of the dot which are in fact
consing dot notation and must be treated as such?

Is the lack of whitespace, in your examples, between the left or right
parenthesis, and the following or leading dot, significant? Does ( . . ) mean
something different from (. .) ?

Also, what is the lexical analysis to make of this?

(. .)
\ /
/ \
( v )

Hmm ....
