[Jprogramming] Indexed assignment must be slow?

[Blake McBride]

Yes, I am picking that up.

One important take-away to this is that in J, when doing indexed
assignments, one should put that code on its own, separate line of
code.  One shouldn't create a "one-liner" by combining it with other
code.  Using indexed assignments in the middle of a "one-liner" causes
a copy.

Does that statement sound right?

Thanks.
