Hi all,

I found a use for tacit trains today: making circle verbs with a sensible
obverse:

   oi =: (& :. ({{-m}} & ].)) o.
   1 oi
1&o. :.(_1&o.)

Nice, but I have a question:
How does one make the {{-m}} part tacit? Or more general, how to make verbs
operate on nouns and use their results in a tacit modifier train? I guess
this could also be useful in experiments like structural under...

Best regards,
Jan-Pieter
