It also makes the function slower. Which may be an important issue
for JSON processing. Callers that don't care about the original list
will be "punished" regardless.
How about adding an optional argument instead, by default off, to
request this behavior? then callers who care about the original alist
could request a non-destructive operation, and others won't suffer any
slowdown.
