Thanks, I'm applying it.

Thanks :)

Yep, but a pain in the neck to implement.  Yet semantics when
conditionals are used is to be defined.

My very humble opinion is that for the time being the current behavior
is the right one.  Once we clean the handling of conditionals etc.,
*if* it appears to be easy to implement, then let's go for it.
Otherwise it's too complex a code to implement for a (IMHO) poor

Once we have that, someone will want to be able to *prepend* instead
of appending etc.
