I disagree.  APL isn't about readability to outsiders (and this is IMO
not a thing every language needs to strive for, sometimes there are
things more important).  Take this piece of J:

  f =: 1:`($:@<:&<:+$:@<:)@.(1:<])

(taken from http://cubbi.org/serious/fibonacci/j.html)
Or, in K:

  fibonacci:{x(|+\)\1 1}

(taken from http://www.kuro5hin.org/?op=displaystory;sid=2002/11/14/22741/791)

Or, again in K:

  fx:{x{x,+/-2#x}/0 1}

(taken from http://www.kx.com/listbox/k/msg05165.html)

These all are far more unreadable to me, even though I know the basics
of APL...

Besides, what is there to maintain about fibonacci?
