Re: (setq unread-command-input 'a) results in infinite loop

[Richard Stallman]

    Please describe exactly what actions triggered the bug
    and the precise symptoms of the bug:

    (setq unread-command-input 'a) 

    results in an infinite loop, also on unix platform

    that's clearly a bug, no?

Setting unread-command-input to a value that is not a list is
incorrect usage, so this isn't really a bug.

One could propose making Emacs more defensive about this particular
incorrect usage, but there are many variables you could set that would
make Emacs cease to work.  Is this one worth it? I haven't seen
many such bug reports.
