Now the graph of `a∧b` is a caret shape and `a∨b` is a vee. ### Acting on windows can be awkward -When taking Windows along more than one axis, acting on the resulting array requires the Rank operator, duplicating either the right argument rank or (negated) left argument count. A nested Windows would only require Each. +When taking Windows along more than one axis, acting on the resulting array requires the Rank operator, duplicating either the right argument rank or (negated) left argument length. A nested Windows would only require Each. ### Group doesn't include trailing empty groups But there are workarounds, described in [its documentation](doc/group.md). dzaima has suggested allowing a single extra element in the index argument to specify the result shape. Another possibility is for the result prototype to be specified to allow overtaking. |
