The only contexts I thought of where this might be a problem would be
Lisp cons literals and the C trinary operator, and maybe the C member
operator.  In all cases handling this smoothly would involve a change
to the end of sentence recognition to require non-whitespace before
the full stop.  I have never seen people use styles like

'(car. cdr)             ;; not a dotted list in Emacs Lisp, anyway
x = bool? val1: val2;
aggregate. member = x;

so I don't think it would be a problem in practice.
