It can be set to any value at all, unfortunately.

The problem now is that non-cons/non-nil values are ignored.
The loop to repeatedly thinks there's input so it consumes 100% = cpu, each iteration seeing that it isn't a cons cell, so there's &q= uot;nothing to do".

Can unread-command-events be anything but nil or a cons cell?=C2=A0 = If not,
we could change the few tests of the value to explicitly ignore
non-nil, non-cons values.=C2=A0 Do you see any immediate problems with such=

That's not what I asked.

Exactly. So these values aren't ignored, they create an illusion that some input is available. I was thinking about ignoring them entirely, i.e. treating such values as nil (and maybe even silently replacing them with nil). The question is: would that kind of change break something?

That's not what I asked.=C2=A0 I asked whether non-nil, non-cons= values
have any meaning in unread-command-events.

<= div>Don't think they do. They are an error.=C2=A0

Exactly.=C2=A0 So these values aren't ignored, they create an il= lusion that
some input is available.=C2=A0 I was thinking about ignoring them entirely,=
i.e. treating such values as nil (and maybe even silently replacing
them with nil).

A= h, sorry I misunderstood originally!

That sounds good to me (though it would be s= lightly better to warn about it somewhere, IMO)

= =C2=A0

The question is: would that kind of change break something?

I think most scenarios it would break would be ones that currently = consume 100% cpu. So besides scenarios like https://xkcd.com/1172/ it is unlikely :)
