On the C level that means: you can put in strings and whatever you put in 
your get out.

On the Perl level that means that we convert any scalars into strings and 
store that. Any special information that was in the perl scalar is not 
stored. So for example if a scalar was marked as utf8, that flag is lost.

That explanation should probably live here:
http://perl.apache.org/docs/2.0/api/APR/Table.html#Description

if the way I've put it is clear, I'll add it there.

I'm not sure I understand what you are talking about, Jie. Are we talking 
about something like $r->headers_in table? In which case it doesn't have 
any query string data, other than the unparsed one, which you should 
get/set via $r->args anyway. If not, please explain.
