'''Works with jq, the C implementation of jq'''
'''Works with gojq, the Go implementation of jq'''
jq has no built-in bitwise operations, but the
[[:Category:Jq/bitwise.jq | "bitwise" module]]
defines
all those needed for the task at hand except for rotations.
Here `rotateLeft` and rotateRight` functions are defined relative to a given width.
The examples are taken from the entry for [[#Wren|Wren]].
