The docs say that letters and *, +, !, -, _, and ? should work anywhere, and
letters, numbers, and *, +, !, -, _, and ? elsewhere than the first
character, while making no guarantees about most other characters and
specifically indicating that / and . will NOT work. (And delimiters -- (, ),
{, }, [, and ] -- won't work, nor will whitespace (including commas), since
they act as token separators.)
In practice, most other characters seem to work, but characters used in
reader macros (#, %, ;, ', `, ~, @, etc.) may not. It is rather odd that %
acts up outside of the #() reader macro though.
And, wouldn't it be nice to get a clearer error-message? :-)
