I don't use array-ref/set! anymore since array-from/amend! generalize them. I
actually use a further generalization in a separate library :p
But I have a proposal below that makes this discussion moot, I hope.
| master (current) | meaning | proposal
|
|---------------------+----------------------------------+----------------------|
| array-from* | look up subarray, even #0(x) | array-slice
|
| array-from | look up cell, so x and not #0(x) | array-cell-ref
|
| array-amend! | set cell | array-cell-set!
|
| array-for-each-cell | iterate over subarrays | array-for-each-slice
|
We define a k-cell to be a (prefix) k-subarray except that the 0-cells are x
instead of #0(x). This is also consistent with the APL/J terminology (there are
no rank 0 arrays in APL/J that are different from a simple element).
(array-for-each-cell) however must iterate over k-subarrays (not k-cells) so
that they can be used as write targets. Then it makes sense to change this name
to (array-for-each-slice), and all the names are consistent.
What do you think?
