Re: segfault after changing max-lisp-eval-depth and max-specpdl-size

[Richard Stallman <rms@gnu.org>]

    That means I'll have to use let/while/setq instead of recursion
    in order to "Avoid arbitrary limits", which produces less
    enjoyable code.

Although max-lisp-eval-depth is an arbitrary limit, the non-arbitrary
limit of the stack size lies behind it.  A program that needs to
recurse for each element in a long or deep data structure really can't
work, in the absence of a tail-recursive interpreter.  If we succeed
in rehosting Emacs on Guile, which is a long-term plan, tail-recursion
would work.  Until that day, you simply have to use iteration.
