I'm talking about the _event_.  The value
of the event is a symbol.  In both cases
(I think) it would be the symbol `M-d'.

(I didn't expect that you did mean that.)

My point (in this tangent discussion) is that
it is possible to drop the angle brackets.
And the result would be a lot less noise.

But unless we also added a convention such as
no single-char function-key names, there could
be some rare ambiguity.

One way to avoid that rare case of ambiguity
would be to use angle brackets only for the
case of single-char names.
