I see what you mean with 4 and 5.

But have you considered the raised arms (kA) ? Lots of groups can be put within the raised arms. 
If  a horizontal group, or even a vertical group is being inserted, and one wants to do this using
vertical grouping + JOIN, there is no guarantee the result will be close to what one expects
(the group being actually inside the bounding box of the raised arms). For me, it feels
right to fit the Hm sign inside kA using VERT+JOIN, which might well 'stick out' above.
But not say the 't', which one expects properly inside, and which moreover is being read 
phonetically after the kA (if that means anything).

This is why I think we should reconsider using insert-inside for such cases. Then also the cobra
could be seen in a new light.

For the syntax without brackets, see attachment. I'm not sure that for simple machinery this is any easier
to process than a bounded number of bracket nestings. Note there are 12 binding values hidden in this
model.

I have left open the exact notation for operator precedence. I see at least four possibilities, as listed in the
document.
