[issue5535] json custom encoder not fully functionnal

[Bob Ippolito]

Bob Ippolito <bob at redivi.com> added the comment:

It is common to specify a default function but it would be terrible for 
performance if this function was called for every single object passed 
through to the decoder.

If you want a serialization different from a primitive type you'll have to  
choose a different base class.

resolution:  -> wont fix
