Hi Inge,

That's right. But there is a difference between having keywords and
having *reserved* keywords. In TMQL we have keywords, but no reserved
keywords. That means, you can use the keywords in other contexts
without trouble.

Aside from the keyword-issue, LEFT, RIGHT and REIFIED LEFT and REIFIED
RIGHT are suboptimal keywords. The arrow < > indicates a direction
to/from a topic/statement. RIGHT and LEFT don't provide that kind of
direction. Users will have more trouble to remember when to use
LEFT/RIGHT vs. <~ / ~>.

I think dropping one tilde (~) would just be fine.

And replacing '<<' '>>' with '/' name-of-an-axis may solve your other issue
as well.

Best regards,
