does give ...
>> test
== ["a" "BBBB" "c" "d"]
and then
>> change test/:i "b"
== "BBB"
>> test
== ["a" "bBBB" "c" "d"]
which may or may not have been then intended action. I ask myself which
result is the *least* surprise, and my guess is that it works correctly as
is. So it seems that
change test/:i "whatever"
is an equivalent action to
test/:i/1
but my expectation of Andrew's proposal would be
test: ["a" "b" "c" "d"]
i: 2
test/:i: "BBBB"
test ; pseudo results ----> ["a" "BBBB" "c" "d"]
I personally would like to see this type of action; I think it would add to
the "intuitive" nature of the language. It is not clear that this behavior
would break some other action/result.
Can anyone else see that it does? Just curious.
Thanks, Paul.
