Elisps rplacd vs CL's one

[Marcin Borkowski]

Hi all,

Emacs Lisp's rplacd and Common Lisp's RPLACD are called the same, but
behave differently (ELisp's one returns the NEWCDR and CL's one returns
the modified cons).  What is the reason for that?  Is it an accident?
While I do understand that EL ≠ CL, having a function called the same in
both, doing roughly the same thing, but not quite, seems a bit
misleading, and I was just curious whether there was a deep reason for
that.

Best,
