Yes, that's true and apropos.

Once you've made the decision to stray from ASCII, a whole new world
of custom operators opens up, along with the nightmare of custom
keyboards (but hey, Princeton had 'em, and APL was the first computer
language I really got to know).

In J, the assignment operator is =: although =. is also meaningful
(local assignment).

= is a comparator.

For more on J, see:

(Iverson himself helped me with this essay).
