DOSUBS with binary operations

I was running:

Code:

:: DUP
DTAG

And I just got DUP on the stack.
Then I ran TYPE on it to get 19 which means:
Built-in command

Or then with * I got 18 which means:
Built-in function

Somehow I've always thought that a program (i.e. \<< … \>>) is similar to quote (or ') in Lisp.
But as it turns out, we can do the same by adding an empty tag to a built-in function or command and then removing it again using the DTAG command.
In both cases the immediate execution is postponed, which is what we want.

Thanks for your explanation: that was enlightening.
