Search.brave.com gave me this back.  Is it correct?
(I fear "AI Slop").

If you are referring to the | symbol in the context of array
slicing or flattening, it can be used in list context to
flatten an array into a list of its elements, but this is
not done by placing | directly in front of the variable name.
Instead, it is used in expressions like |@array to flatten
the array into a list.
