^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.
