You  explain what  ^t.  does, but what does  t.  do?

    t. i.6
|syntax error
|       t.i.
   1 t. i.6
|length error
|       1 t.i.6
   ^t.

   ^t.
%@!

This is all that t. does -- it's up to you how you use it.

   %@! i.6
1 1 0.5 0.166667 0.0416667 0.00833333
   1 %@! i.6
_ 1 0.5 0.333333 0.25 0.2

The first sentence is an example how this mechanism was intended to be used.
The second sentence is just coincidence -- the result of t. was not designed
to deal with a left argument.
