-----------------------------------
Oops, remove that first 'This is not an issue". Instead, this is an issue, but
not because of what you think.
It may have worked for you before that commit, but that is because I changed
the conversion system to use json when converting to/from map/list, but this
was a change that Adrian said shouldn't be done(and I agree with him).
