Period (I think) and digits (definitely) must all be catcode other to  
work inside numexpr and so on. I wish it were otherwise, but I don't  
think it's nice to have to use scantokens to sanitise input for all  
numeric work.

~ is currently catcode space in expl3 since space itself is catcode  
ignore. So I don't think this suggestion is feasible either.
