J is very expressive (in the formal sense), which has the effect that many
meaningless sentences are legal, so you do get less immediate feedback on your
mistakes. Modifier trains are a recent prominent example of this, but not the
only one; for instance, I recently chatted with somebody who wanted 0 p: = 1
p: to do something reasonable (wanted 0&p: = 1&p:), and I think there is a
similar (though less extreme) example in some introductory material on the
wiki.

I was looking over https://rosettacode.org/wiki/Gotchas#J today, and
wondering if that writeup was missing anything important.
It occurs to me that other people might have better perspectives on
this, than I do.
Does anyone here see anything important that got overlooked?
Thanks,
