Comment (by archblob):

 I have added a working, validated patch. It can be reviewed and I'll make
 the necessary modification if all is not well. Otherwise I think it can be
 merged and I've also added tests.

 It does not include the fix for {{{:kind}}} because I thought it would be
 best to separate them. I will include another patch for that after we are
 done with this one.
