I'm not opposed to something like this either, however having actual
attributes inside curly braces here looks strange. I don't think
attributes are used in this way anywhere else.

If this is the case, then removing assignment from the declaration of
all the stdlib operators could also be part of this proposal, or broken
out into a separate one if necessary.
