Hi Blake,
I believe the ⎕ES related bugs reported recently should be fixed in SVN 372.
This one is not, though. The reason is that fixing it would have
considerable performance
impacts (we would need a copy of every defined function argument only
for the rare case that ⎕ES
is called),
I also find it somewhat arbitrary to show a non-locked function as
locked in this very specific case.
Since ⎕ES is not ISO-standard anyhow, I take the freedom to trade
performance for APL2 compatibility.

⎕ES is showing the modified and not the original argument passed to
the function. IBM APL 2 displays the original argument passed.
Thanks.
