I've never tried it, but would be very surprised if it has
ever worked.

What would the following do?
mymacro = {\override Foo #'fie = #fum \override One #'two = #three }
{ c4 \once \mymacro c4 }
Not to mention
mymacro = {c d e \stemUp }
{ c \once \mymacro }
If we allowed for the syntax, we would have to figure out something
sensible to do in all these situations.
