If we get rid of those exceptions the separator problem will go away. But then math will be messed up. The problem is that the
+ - .
are ambiguous; sometimes they have a mathematical significance; sometimes a separator significance. We need the exception for math (generally done the usual l-r way) but don't need it for separators (done in the r-l way).
Ambiuity is no good; for luatex and beyond we need to consider using the 2200 unicode block for math mode and not the math-like symbols from the 0000 basic latin block. Then the entire problem goes away. punctuation is punctuation; math symbols are math symbols. In TeX the ambiguity is built in since it apparently maps the ascii punctuation to math, which is anachronstic.
