I see. Well, I find the term "direct-" awkward. TMQL introduces a
terminology which does not exist outside of TMQL (neither in TMDM nor
TMRM nor (to my knowledge) in any other knowledge representation
system) and I wonder if the mentioned use cases are common enough to
satisfy a shortcut in TMQL. I guess my answer would be "no" and I
wouldn't make these axes/paths first class citizens in TMQL.

Best regards,
Lars
