Ah neat, thanks! I'll research and try it and come back if I have 
questions. :D

Maybe I didn't explain myself well. The exported procedures already 
accept a per-request reader/writer that overrides the default 
reader/writer. I was thinking that maybe it's worth making the /default/ 
reader and writer an instance variable as well, instead of using 
lunajson.  So I don't see why it would be significantly hard, and why 
the number of different libraries and interfaces matters.  Of course the 
user must provide a reader/writer that satisfies a certain interface 
(e.g. the reader has to accept a string as input, and output whatever 
structure they want).

Thanks for taking a look!  You mean in the function `String`? I think I 
put that comment before writing the function that converts a table to a 
query string; since that function already URI encodes the given values, 
there's no need for anything else.
