Think nothing of it.  I was back in the highschool today, talking linear algebra to the very top layer of the high-performing students, having them write proofs on the board. It is obvious that the distinction between "its" and "it's" is not observed in practice, even among these kids who are tomorrow's elite.  It will be gone in another 100 years.

Back when I was teaching Latin, I tried to give examples of the difference between transitive and intransitive verbs in English. I started,

We say "I lay the book on the table: I lay it, I laid it yesterday, I have laid it there many times."

We say "I lie down for a nap.  I lie down, I lay down yesterday, I have lain down..."

the rest of the sentence was drowned out by cries of "No!".  They had never heard such a thing.  My conclusion: "lie" is dead. Write it off.

I have already written off "whom".  The language evolves.

Sorry for the noise,

(a,a=.?@#) is a verb, namely (?@# , ?@#). In this expression a is set to the 
_verb_ ?@# and then train (a,a) is evaluated.

In the second case a is set to the _result_ of ?@# and then (a,a) is evaluated. 
To do this tacitly:

(] , ]) @ (?@#)

or more concisely

,~@?@#

or equivalently (how I would write it)

2 $ ?@#

As Henry said, to store an intermediate value in a verb's evaluation for use 
_after_ it's application, you must use an explicit verb, for example:

,~ @ (3 : 'a=: y') @ (?@#)

Hello, simple question.

This behaviour surprised me.

  (a,a=.?@#)'01234'
2 4

  3 : 'a,a=.?@#y' '01234'
1 1

Why a is not equal to a in the first case? How can I save the roll as an 
intermediate result in the tacit version?
Thanks.
